Amazon has a new plan to revolutionize the way we all grocery shop. And it's all about this little device, meant to replace pretty much everything you would do in a physical store.

It's called "Amazon Dash." My wife and I have been using Amazon's grocery service for a few months now and generally we are fans. Fresh Direct doesn't seem to have as good of a selection, at least in our area, and Amazon is just the slightest bit more convenient (and a little cheaper too).

During our last order, the company offered to let us use the Amazon Dash program for free. It's free for those invited right now.

The idea behind Dash is that you use the device to do all your ordering anywhere in your house, and then send it over to the Amazon Fresh app for easy ordering.

It's really ambitious, and not at all perfect.

Here it is: Amazon Dash. It comes in this nifty little black box with a comprehensive guide.

Open it up, and this is what you get. The Dash device is a wand type thing with a couple buttons. Oh and thank you, Amazon, for including AA batteries.

First things first: take the thing apart and put in the batteries.

NOW WATCH: Forget the Apple Watch — here's the new watch everyone on Wall Street wants

To be successful in the technology-driven internet age, a company has to attract "smart creative" employees and then create an environment where they can thrive. 

At least that's the argument that Google's Eric Schmidt and Jonathan Rosenberg make in "How Google Works."

In the book, executive chairman and former CEO Schmidt and former SVP of product Rosenberg outline what they learned while building Google into a company now worth hundreds of billions of dollars. 

The duo created a fun, illustrated presentation to highlight the main principles of the book.

Google gave us permission to republish those slides here.

If you've got just a few hours to boost your business savvy, we've got you covered. These 11 documentary films offer in-depth looks at entrepreneurs, companies, and big ideas you might only be superficially familiar with.

From a film on Wal-Mart's business practices to one on aspiring sommeliers, each will simultaneously entertain and educate you about business.

What it really takes to launch a company

If you think that starting and building a company is like a real-life version of "The Social Network," think again. The 2014 documentary miniseries "startupland" takes viewers through the development of five businesses enrolled in a tech accelerator, showing how scary the experience really is. Each episode features interviews with well-known business execs and entrepreneurs, including Reddit's Alexis Ohanian and AOL's Steve Case. (The feature film "startupland," from the same creators, comes out this year.)

How a personal-care line became an accidental success

The face on Burt's Bees products belongs to Burt Shavitz, a beekeeper who never anticipated that he'd found a billion-dollar international brand. "Burt's Buzz" tells the story of Shavitz's career, starting from his days as a young New York City photojournalist. Viewers also learn about Shavitz's complicated relationship with cofounder Roxane Quimby, who eventually bought Shavitz out and sold the business to the Clorox company.

How to turn your passion into a profession

"Somm" follows a group of four men preparing for the master sommelier exam, a test with one of the lowest pass rates in the world. Their obsession with getting ready for the exam consumes them as well as the people closest to them. The film will inspire you to pursue your own ambitions, however lofty they may seem.

When it comes to building franchises, Hollywood tries desperately to stay consistent. If the first movie is a hit, studios will try their hardest to keep the same directors and actors on board as long as possible.

But there are instances in which change is necessary. Sometimes for the betterment of a movie, but sometimes they leave viewers scratching their heads.

From "Batman" to The National Lampoon "Vacation" franchise, check out the most notable recastings in movie history.

In 1980's "Star Wars: The Empire Strikes Back" we see the Emperor for the first time as he speaks to Darth Vader via holograph. The Emperor was actually played by Elaine Baker, then wife of special makeup effects legend Rick Baker. The voice was done by New Zealand actor Clive Revill.

For the next film in the saga, "Return of the Jedi," George Lucas recast the role with Scottish actor Ian McDiarmid, who not only went on to play the Emperor in the prequels, but was placed into the "Empire" scene when Lucas updated the films in the early 2000s.

Though Anthony Hopkins won an Oscar for his performance as Hannibal Lecter in "The Silence of the Lambs" (and would play the part two more times), he wasn't the first to star as the good doctor.

If you want to see how astronauts will mine the Moon, anchor an asteroid, or drive rovers on Mars, then look no further than the NASA Extreme Environment Mission Operations, or NEEMO.

NEEMO is the only undersea research station in the world, and astronaut crews have been training with it ever since the facility was first established in 2001.

Resting on the Atlantic ocean's seafloor, 62 feet below the surface and 3.5 miles off the coastlines of Key Largo, Florida, NEEMO offers astronauts the closest environment to outer space they can get without strapping themselves to a rocket.

When they're under the sea, these astronauts train for NASA's most prestigious upcoming missions — in some sense, you need to learn to be an aquanaut before you can become an astronaut.

Here are some of the incredible things these sea-faring explorers do while they're getting they're feet wet for space.

First thing's first: The aquanauts have to get to their undersea station. They do this, naturally, by plunging into the Atlantic.

As they approach their new home, each astronaut crew will see the main base, called Aquarius, loom into view through the clear-blue waters.

Aquarius only has enough room to accommodate up to 7 people at a time and each mission lasts no longer than 3 weeks. Shown here are four members of the NEEMO 10 crew who stayed from July 22 through 28 in 2006.

This photo shows NEEMO 10 crewmembers they reach Aquarius. From front to back are Karen Kohanowich, deputy director of NOAA's Undersea Research Program, Silver Spring, Md.; Japan Aerospace Exploration Agency (JAXA) astronaut/aquanaut Koichi Wakata; and NASA astronaut/aquanauts Karen L. Nyberg and Andrew J. Feustel.

Leave it to San Francisco to disrupt the foundation of a well-balanced breakfast. Toast is beginning to go the way of chocolate, cheese, and coffee — becoming "artisanal."

The Mill, a café and bakery near the Alamo Square neighborhood of San Francisco, sells slices of toast that make the mushy slices of Wonder Bread from your childhood look like water crackers.

The Mill's inch-and-a-half-thick slabs of doughy goodness are toasted on high and served with locally sourced butters and jams.

And they come at a price — a whopping $4 for a single slice.

Not surprisingly, the media has not been kind to the trend's proprietors, saying that it reaches "an incomprehensible level of pretentiousness." We spoke with The Mill's co-owner and toastmaster Josey Baker — yes, his real last name is Baker and his title is "toastmaster"— about why artisanal toast is the greatest thing since sliced bread.

In summer 2011, Baker, a born and raised Vermonter, got an invitation from the founder of a local coffee chain, Four Barrel Coffee, to collaborate on a café near Alamo Square. Baker had previously been baking bread in his home kitchen and delivering loaves to bakeries, pizzerias, and grocers on his bike.

Baker's answer to the collaboration question: "After I s--- my pants I told him yes."

As the café — which is now a sunbathed space with wood-beam ceilings and graphic prints on the wall — was being built, Baker ran a pop-up tent on location. They wanted to offer customers something to eat with a cup of coffee, and since Baker didn't make cookies, croissants, or muffins, he brought his toaster from home and got to work.

"At that point, it wasn't, like, 'We're going to become known for our toast.' It was my way to eat bread, and people responded strongly to it," Baker says.

The toast quickly picked up momentum, thanks in part to Baker's simple combinations of toppings. "Growing up, I would eat toast with butter and cinnamon sugar," Baker says. "It's actually not very creative, but it did seem to strike a chord with people."

The Country bread, which uses a blend of bread flour and whole wheat, sourdough culture, and sea salt, is prepared Baker's way. Quickly after introducing the dish, it became The Mill's first runaway hit.

Today, The Mill serves 400 slices of toast on the average weekend day, with as many as six four-slice toasters going at once. The menu has three toasts and a weekly special, based on seasonal ingredients. Customers can mix and match spreads, such as almond butter, strawberry and blackberry jam, maple syrup, and a housemade version of Nutella.

Each loaf takes about 48 hours to complete, and it all begins with the grain. A beautiful birchwood mill sits in a closet-sized room and grinds 300 pounds of whole grains into flour every day. They never sift out the germ, the part of the grain that contains many B vitamins, protein, minerals, and healthy fats, so the bread keeps its nutritive qualities.

The Mill uses a lot more water in its recipes that most bakeries, because a moister dough makes for a moister bread. This does make it more difficult to shape the loaf by hand, however.

Breads bake in the oven between 30 and 120 minutes depending on the size and type. They emerge crispy on the outside, with burnt ends adding texture and flavor, and soft and chewy on the inside. Finished loaves never sit out more than a day and a half.

While whole loaves are The Mill's bestsellers, it's the toast that draws people in.

One of the most popular items, the Dark Mountain Rye, uses 100% freshly milled whole rye grain and is chock full of sea salt and sesame, sunflower, and flax seeds. It's topped with cream cheese, salt, and fresh ground pepper.

The bakers encourage substitutions and original combinations of toppings. This customer ordered the Whole Wheat Bird Bread, made with millet and sunflower seeds, slathered in almond butter and sprinkled with salt.

I ordered the No. 2, a slab of Whole Wheat Bird Bread with melted butter and strawberry jam, running me the aforementioned $4. My mouth watered watching it come together at the toast bar.

The toasters looked like they would belong on my kitchen counter — nothing fancy. My piece of toast went in for about a minute before being flipped and cooked an additional minute.

Order up! The melted butter and strawberry jam ran over the sides, and it was beautiful.

At first, I was surprised by how difficult it was to cut the crust with a butter knife. Baker wasn't kidding when he said he likes the ends burnt. But the crispness added a contrasting texture to the spongy, still warm center, making for a perfect combination.

The bread itself reminded me of the quintessential whole wheat — nutty, brown, and malty — and yet, it was a far cry from the factory-made multigrain bread I buy at the grocery store. It tasted whole and unprocessed, bursting with the natural flavors of millet and sunflower seeds.

With each bite, I sopped up strawberry jam run-off. The tartness enhanced rather than overwhelmed the bread.

As someone who pays more than $4 for bagel sandwiches regularly, I found The Mill's artisanal toast a worthwhile expense. It contained high-quality ingredients, sourced responsibly, and cost less than some sugar-coated pastries at Starbucks. Most significant, the toast reminded my taste buds of the big pancake breakfasts I shared with my family in New Hampshire. It tasted, well, wholesome.

I would gladly fork another $4 again.

"For me, toast is comforting, unintimidating, and delicious. It's the same experience for most people," Baker says. "We take something very simple and try to nail every aspect of it ... You've encountered [toast] a million times in your life, but this is the best you have had."

You be the judge; visit The Mill, at 736 Divisadero St. in San Francisco.

NOW WATCH: How To Make The Perfect Grilled Cheese

The leaders of the most successful tech companies need a lot of skills. One of them is leadership. They must inspire teams of employees to carry out their daring visions against incredible odds.

That means they offer some great advice.

We've compiled quotes from 19 of the biggest names in tech. Some are investors; others are founders, CEOs, or executives at the most renowned tech companies in the world. Their words will inspire you to achieve more in work and in life.

I had to see what all the fuss was about.

Back in March, Jay Z's big streaming music service launched. He calls it "Tidal."

Jay Z spent $56 million to buy Aspiro, the Swedish company behind the WiMP and Tidal streaming sites. Since then, he and his team have made it their own.

But the PR battle for Tidal has been real, with haters coming out of the woodwork to bash the music service, including well known musicians like 50 Cent and Death Cab for Cutie, among others.

Enough. It was time for me to find out for myself. I downloaded the app, buried my Spotify icon deep within my iPhone, and got to work.

Here's the first thing you see when you open the app. This is honestly the most useless part for me. It mostly focuses on exclusive content and I've noticed an aim towards hip-hop (despite Jason Aldean being featured here). That goes against my personal tastes, but maybe it appeals to you.

While that's not super helpful, the rest of this app is fantastic. Here's the sidebar you see inside the app which is, in my opinion, much more useful than Spotify's sidebar. It's especially easier here to navigate to the songs you save offline and get to specific genres of music.

There is a lot of focus on curated playlists here which is a great feature for Tidal to have. As you can see they split playlists up into categories based on where you might be or what you might be doing. It's a clean, fun interface.

Today’s roller coasters tempt and terrify in equal measure with names like Mind Eraser and Intimidator 305, boasting hairpin turns, heavy drops and insane speeds of up to 149.1 miles per hour.

But nothing beats a classic.

We've found 9 of the oldest roller coasters around the world. Most of these rides date back to the early 1900s, and you can still ride them today. 

Leap-The-Dips (1902)

Lakemont Park, Altoona, PA

This tamely named wooden rollercoaster hails from 1902, and though it closed in 1986, the US National Historic Landmark reopened in 1999.

It’s only 41 feet tall, and its average speed of 10 miles per hour will barely ruffle your hair.

Scenic Railway (1912)

Luna Park, Melbourne, Australia

While not the oldest roller coaster in the world, the Scenic Railway is the world’s oldest continually operating one. Its dips and turns may leave you unfazed, but its stunning views of Port Philip Bay won’t.

Rutschebanen (1914)

Tivoli Gardens, Copenhagen, Denmark

The Rutschebanen may be the main attraction in the world’s second oldest amusement park (built in 1843), but it was originally designed for the Baltic Fair.

To this day it retains an operator who manually brakes the 2,051-foot ride, keeping it at a mellow 36 miles per hour.

It costs a lot of money to shop at Whole Foods.

The company has earned the nickname "whole paycheck" it's high prices.

But it doesn't have to be that way.

We picked up some tips from money-saving experts on how you can save. 

Get comfortable in the kitchen first.

There's a lot of preparation needed before making an efficient trip to an organic grocery store.

"If you know how to cook and you plan ahead that grocery shopping on a budget, even organic, can be much more feasible,"Jess Dang of Cook Smarts, a meal planning company that specializes in budgeting for healthy food, told Business Insider.

"The way that I think about it [...] you want to take advantage of sales [...] even if things aren't on sale — x is cheaper than y at the grocery store. I think people get really afraid about making substitutions, even if they go in with a list, because they've planned ahead with all of these recipes, and they see that 'oh, actually this is on sale, but what I need is red peppers' — they're afraid to make that swap."

"Having a good knowledge of cooking [allows you to] feel comfortable you can make a swap based on sales or based off of better prices," she said. Ultimately, it "allows you to take advantage of better deals and save money." 

Check your pantry before you go to Whole Foods.

"If you have that well stocked pantry [...] you actually don't have to be adding very much every additional week," Dang said, while also adding you should just be "checking what pantry things you need to replenish."

"It shouldn't be that every time you go shopping you need to buy a ton of pantry goods," she said. If you know what's in your pantry, you won't have to splurge on a ton of things you don't need, saving you money right off the bat.

Look for sales, and remember the importance of Wednesdays.

Looking for sales is a given, right?

But Molly Siegler, content editor at Whole Foods, informed us there are specific days items go on sale, which is important to keep in mind when preparing a shopping trip. "New weekly sales start on Wednesday and run through the following Wednesday, so there are actually double sales every Wednesday!" She told us. "Stores regularly have one-day or weekend sales on specific items— from packaged goods to fresh produce to wine and beer."

It's also important to look for sales before you go, and then make your meal plan around the deals that will be present rather than succumb to what's in front of you. Siegler pointed us to Whole Foods sales flyers, which are readily available online, and The Whole Deal, which has ample coupons and deals.

Can't stand the big boss at work? Try getting a job at Google, Nike, or Goldman Sachs.

Employees at these companies have three of America's most beloved CEOs.

That's according to a new report by Glassdoor, an online jobs and careers community. The 2015 Highest-Rated CEOs report relied solely on the input of employees who elected to participate anonymously in an online company review survey.

Respondents were asked to rate their CEO and say whether or not they approve of the way he or she is leading the company. 

To be eligible for the final ranking, each CEO had to run a company with at least 1,000 employees, and had to have at least 100 approval ratings, senior management ratings, and company reviews between April 2014 and April 2015. 

25. Corey Schiller (and co-CEO Asher Raphael)

Company: Power Home Remodeling Group

Approval rating: 91%

Employee testimonial: "The management here is unmatched with how well things are run, how they treat us (pay, bonuses, vacations) and just in general how cool they are." 

24. Omar S. Ishrak

Company: Medtronic

Approval rating: 91%

Employee testimonial: "Mission of company is very admirable and truly what most employees and absolutely the CEO stand by, 'alleviate pain, restore health, and extend life.'" 

23. Martin Mucci

Company: Paychex

Approval rating: 91%

Employee testimonial:"The CEO is also awesome and you can tell he truly wants the best for the company AND the employees."

Just a few short years ago, unknown British actress Emilia Clarke had just two filming credits on her résumé: walk-on roles in a soap opera and a made-for-TV movie.

July 1, Clarke reprises the role of Sarah Connor in "Terminator Genisys."

Born in the fall of 1986, Emilia Clarke grew up in the picturesque county of Buckinghamshire, in the south of England.

One of the largest camera trap studies done in the Serengeti National Park, Tanzania, reveals the daily lives of its wild inhabitants as they eat, play, nap, and even take inadvertent selfies.

The scientists of Snapshot Serengeti mounted 225 cameras in a 434 square mile area as an expansion of the ongoing Serengeti Lion Project and the Tanzania Wildlife Research Institute's surveys of major species. 

The cameras captured 1.2 million sets of photos (three photos per set) from June 2010 to May 2013, according to the study published on June 9 in Scientific Data. They've set up a website can search the whole set of images to find your favorites.  

What they uncovered gives us an idea of what the daily struggle to survive looks like in one of the most varied and unique ecosystems in the world.

1.6 million wildebeest and zebra migrate across the Serengeti savanna every year. Hoping to catch this awesome show of life, the research group Snapshot Serengeti set up camera traps in the park, which were set off by a combination of heat and movement — catching lots of images of animals in motion.

Source: Scientific Data.

... Like this herd of elephants migrating. Many of the 322,653 photos that contained wildlife shows groups of animals. "The images are supposed to be random," Swanson said. "We wanted the cameras to give an unbiased view of how these animals were using the landscape."

Snapshot Serengeti was stunned by the 1.2 million photos captured. "We were simply overwhelmed." So, they partnered with Zooniverse, a citizen science project website, to have volunteers sort through the images. But using non-scientists leaves a lot of room for mistakes when identifying animals. For example the hyenas below are easily recognizable ...

The world's most valuable company doesn't just confine its activities to America. It's also working hard in China and emerging markets, and has an extensive network of factories and acquisitions in Europe.

Apple has an important new factory in Ireland, and it has acquired several UK and European tech startups, in addition to its retail stores and offices around the continent.

But that's not all it does here.

Novauris Technologies - the heart of Siri

Novauris Technologies formed a major part of Apple's Siri personal assistant. The company started in 2002, composed of former employees from popular dictation company Dragon Systems. Novauris created accurate speech recognition technology that could work out what you were saying on your phone, meaning that voice input didn't have to be sent to servers to decipher.

Like many of Apple's acquisitions, the fact that Novauris had joined Apple was meant to be a big secret. But the company gave the game away when a TechCrunch reporter called its office in 2014 and someone answered the phone with "Apple."

It looks like the company's technology is now being used as part of Siri. CEO Yoon Kim now lists on his LinkedIn profile that he manages Siri at Apple in San Francisco.

Holyhill factory - makes iMacs

Apple is expanding its factory in Hollyhill, Cork. The facility combines both an office and a sprawling factory that's being used to assemble iMac computers.

The Irish Independent reported that Apple is undergoing "major expansion" of its Irish office, and it invested €300 million into the development. One local resident says that Apple "basically owns an entire hill" in Cork.

Hollyhill - building driverless cars?

There's a slim chance that Apple could be using its factory near Cork in Ireland to build the rumoured Apple driverless car. It's hiring as part of the factory expansion, and the roles it's hiring for seem to be connected to the automotive industry. That's not proof in itself, though. 

But if Apple were to develop a car, then it would want to do it in secret. Where better to do that then on Apple's very own hill in Ireland?

China's crazy growth has been one of the biggest stories over the past several decades.

But the Chinese economy certainly isn't the only one posting huge growth rates.

We compiled a list of 13 countries with the highest projected compounded annual growth rate (CAGR) from 2014 through 2017 based on the forecasts from the World Bank's Global Economic Prospects.

Keep in mind that the fastest-growing economies typically aren't among the largest, most developed ones. In fact, most of these countries suffer from high income inequality, low levels of per capita gross domestic product, elevated political instability, and rampant corruption.

13. China

2015 GDP: +7.10%

2016 GDP: +7.00%

2017 GDP: +6.90%

2014-2017 GDP CAGR: +7.10%

Economy: China is a manufacturing powerhouse and exporter, and many believe that its economy will surpass that of the US within the next decade. The government faces major problems, however, as the country transitions into a consumption-based economy. Additionally, per capita income is below the world average.

12. Rwanda

2015 GDP: +7.00%

2016 GDP: +7.00%

2017 GDP: +7.50%

2014-2017 GDP CAGR: +7.12%

Economy: Ninety percent of the population works in subsistence agriculture or mineral agroprocessing, while tourism, minerals, coffee, and tea round out Rwanda's economy. Though the country has taken significant steps forward since the 1994 genocide, 45% of the population still lives below the poverty line.

2016 GDP: +7.10%

2017 GDP: +7.10%

2014-2017 GDP CAGR: +7.15%

Economy: Tanzania has recently seen high growth rates because of gold production and tourism. The economy also runs on telecommunications, banking, energy, and mining, as well as agriculture. In terms of per capita income, however, the country is one of the poorest in the world.

Some entrepreneurs who have made billions off of their tech ventures like to spend them in some pretty extravagant ways, whether it be on private planes, summer homes, or even an entire island. 

Others turn to more-philanthropic efforts, choosing to donate their wealth to different causes through foundations and trusts. 

We've rounded up some of the most generous people in tech, all of which have decided to donate large portions of their wealth to charity rather than leave all of it to their children. 

Microsoft cofounder Bill Gates

Gates has been open about his decision not to leave his $84.9 billion fortune to his three children. They will reportedly inherit just a small slice, about $10 million each.

"I definitely think leaving kids massive amounts of money is not a favor to them,"he said in a Reddit AMA in February. 

He founded the Bill & Melinda Gates Foundation in 1994, and it currently has more than $36 billion in assets. Gates also teamed up with longtime friend Warren Buffett to start a campaign called "The Giving Pledge," which encourages other billionaires to donate at least half of their fortune to charity. 

AOL cofounder Steve Case

Case helped millions of Americans get online, and now he's donating much of his wealth to developing other technologies.

He founded the Case Foundation in 1997, which focuses on using technology to make philanthropy more effective. He also started an investment firm called Revolution, which invests in startups outside of Silicon Valley, and signed the Giving Pledge.

"We share the view that those to whom much is given, much is expected. We realize we have been given a unique platform and opportunity, and we are committed to doing the best we can with it," he and wife Jean wrote."We do not believe our assets are 'ours' but rather we try to be the responsible stewards of these resources."

Salesforce CEO Marc Benioff

Benioff recently launched a campaign called SF Gives, which challenged tech companies to raise $10 million for San Francisco-based nonprofit programs in just 60 days. 

He's encouraged other corporations to follow his 1/1/1 model, which says that a company should donate 1% of its equity, 1% of its employees' time, and 1% of its resources to philanthropic efforts.

He and wife Lynne have also personally given a total of $200 million to the children's hospital at UCSF. 

Bill Gates, Larry Ellison, and Jeff Bezos are among some of the wealthiest tech tycoons here in the US. 

But there are plenty of extremely wealthy tech executives across the globe who are making major contributions to their country's tech scenes.

With the help of Forbes' Billionaires List, we've rounded up the wealthiest tech tycoons in 14 countries across the globe. Each has played a major role in technological advances around the world, raking in billions while doing it.

Brazil: Eduardo Saverin

Net worth: $5.1 billion

Background: Saverin became a billionaire after cofounding Facebook with Mark Zuckerberg. He was born in Brazil but attended school in the US before renouncing his American citizenship and moving to Singapore in 2012. He still owns about 53 million shares of Facebook stock and spends his time as an angel investor.

Canada: Garrett Camp

Net worth: $5.3 billion

Background: Calgary native Camp cofounded StumbleUpon in 2002, when he was still a graduate student. After selling the company to eBay for $75 million in 2007, he went on to start Uber with Travis Kalanick. Uber was most recently valued at more than $50 billion. 

China: Jack Ma

Net worth: $25.3 billion

Background: Ma is the founder and executive chairman of Alibaba, the Chinese e-commerce company whose $25 billion initial public offering set a record for the New York Stock Exchange in 2014. He grew up poor in communist China, failed his college entrance exam twice, and was rejected from dozens of jobs, including one at KFC.

Randi Zuckerberg, CEO of Zuckerberg Media and sister to Facebook chief Mark, has sold her Los Altos home for $6.549 million, according to Redfin. 

The home sold only one week after being listed for $5.488 million, property records show. The final sale price was about a million dollars more than what the listing team at DeLeon Realty was hoping to get for the house. 

You'll find plenty of bold colors inside this home, from deep purple bookshelves to a lipstick-print wallpaper in the dining room. 

Zuckerberg is rumored to be making a move to New York City. 

The 6,426-square-foot home sits behind a gate and is shaded by trees.

Rose bushes form an arch in the front yard.

It makes for a beautiful entryway.
