As we've seen in Jonathan Kramer's "The Kimchi-ite" series, South Korea is a country that embraces both its past and its future. That notion is captured perfectly in this Photo of the Day from Flickr user and photographer Ohad Ben-Yoseph, which depicts a colorful old temple set against a sparkling new skyscraper in perfect juxtaposition. Ben-Yoseph's Flickr photo stream is filled with similarly evocative photographs, showing a country in transition.

Three years ago, adventurer, entrepreneur and activist David de Rothschild sailed from San Francisco to Sydney on a catamaran made of 12,500 reclaimed plastic bottles.

His goal with the Plastiki project was to bring awareness to environmental issues like global warming and plastic pollution, and he has continued to stay active in the environmental movement. Most recently, de Rothschild signed on as an advisor to WHOLE WORLD Water, a three-year campaign that aims to unite the hospitality and tourism industry to combat global clean water issues.

Launched on March 22 to coincide with World Water Day, WHOLE WORLD Water uses a social enterprise model to generate funds for the clean water movement. The process of signing on is relatively simple. First, hotels and restaurants sign on to the WHOLE WORLD Water campaign for a nominal per-property fee. Then, they use the suggested Vivreau water filtration system to filter, bottle and sell their own water to guests. Finally, they donate 10 percent of the proceeds to the WHOLE WORLD Water fund, which benefits safe, sustainable clean water projects in the places that need it most.

Founders Karena Albers and Jenifer Willig estimate that if the world's three largest hotel groups joined the campaign and sold just one bottle of water per day, the campaign could raise up to $1 billion for its mission, while contributing up to 25 percent toward the company's bottom line. The campaign has already signed on a number of well-known hotel groups, including Virgin, Dusit and Banyan Tree, along with a number of restaurants, nightclubs and Ritz Carlton properties. Advisors include high-profile names like Virgin mogul Sir Richard Branson, designer Yves Behar, actor and filmmaker Edward Norton and de Rothschild.

Today's multi-image Photo of the Day features scenes from an overnight camel safari in the desert surrounding Jaisalmer, India. Instagram user LankaEdited used a photo collage smartphone app to share different snapshots from her adventure, then added the "Rise" filter to the finished collage for a vintage effect. Apps like PhotoGrid or InstaPicFrame make it easy to achieve this type of multi-image storytelling, which is becoming ubiquitous on platforms like Instagram.

Today's safari-themed Photo of the Day was taken with Instagram and submitted by The Purple Passport, a travel start-up that publishes web-based guidebooks on the world's most exciting cities. The Purple Passport already has guides to New York, Los Angeles, Palm Beach, London, Paris, Beijing and Taipei. Might Abu Dhabi be next?

"Donde esta el autobus por Tlocolula?"

The question was met with a quizzical look. Where was this gringa trying to go?

Perhaps I wasn't pronouncing it correctly.

"Tloco... Toco... Tlaca..." I stammered.

"Ah, Tlacolula."

Si. There.

I don't suppose the makeshift bus stops on the highways of Oaxaca state see many tourists. But somehow, through a series of bumpy bus rides and a long stretch of walking along the side of the road, I had arrived at one.

Earlier in the day, I had decided to escape Oaxaca city for the villages of the Valle de Oaxaca, a vibrant region filled with talented craftsmen, small workshops and stunning scenery. I had discovered that the Tlacolula held a weekly Sunday market, but all attempts to secure a private bus in town had failed – not many tourists visit the small town, about an hour and a half east of the city.

So instead, I decided to try public transport. In time, I found the right bus, and after a cramped hour-long ride I disembarked at a small, dusty station.

Sometimes, you just need to get out of town. It doesn't matter where, so long as it's far away.

For these kinds of trips, flexible travelers can now avail themselves of a new booking platform: GetGoing.com.

The site, which celebrated its public launch yesterday, features an innovative Pick Two Get One platform, which provides airfare discounts of up to 40% if travelers can prove that they are flying for leisure by being flexible about their destination.

Here's how it works:

- Search for the type of trip you want to go on. It can be a geographic region, like Europe or Asia, or a more general theme, like "History and Culture" or "Beaches and Sun."

- Select two destinations from the options provided to you, then select two potential itineraries. At this point, you can see the discounted fare you will receive, but not the airline.

- Fill in your traveler details and credit information, then hit "complete this purchase" and let GetGoing decide where you'll go.

I recently test-run the platform for an upcoming trip to Europe in May. Some of the discounts were significant, like $854 to Tel Aviv ($211 discount) and $631 to Moscow ($146 discount). But most fares were about on par with what I found by searching discount engines like Skyscanner and Kayak. And since the engine is airline-blind until the deal is done, you can't factor frequent flier mileage programs into your deal search equation.

"Sometimes in the morning, when it's a good surf, I go out there, and I don't feel like it's a bad world," Nobel Prize-winning chemist Kary Mullis famously said.

Today's Photo of the Day from Flickr user Jason Rodman captures the essence of that quote. Somewhere north of San Francisco, a lone surfer prepares to enter an ocean devoid of worries and distractions. There aren't any surf-worthy waves, but if you look hard enough you can glimpse the ripple of one on the horizon. It's a photo filled with hope and possibility; a photo that evokes the spirit of the sport.

On a recent Saturday, the streets were filled with bicycles. Bells rang and horns sounded as the cyclists wound their way throughout the city like a moving train of youth and energy.

This wasn't in Portland, or Paris, or any of dozens of bicycle-friendly cities around the world. This was in Guatemala City, a city known more for its violent crime rates than its progressive bike culture.

But one group is trying to change that. Biketun is a new organization started by Javier Mata and Lucia Pivaral with the purpose of promoting a more sustainable way of life and transport in Guatemala.

The group's signature event is a nighttime bicycle tour of Guatemala City. The first was held in December and drew around 250 people. The second, held in February, drew more than 500. The goal is to one day attract 10,000 cyclists to Guatemala's streets.

According to Pivaral, Biketun's mission is to show the country that a better lifestyle is possible - "a lifestyle in which Guatemalans own not only public spaces, but most of all, our freedom. A lifestyle in which we can go out on our bicycles, go to the park, walk on the streets, and interact with different people without any worries."

I inhale. The scent is earthy, smoky. I take a sip, rolling the liquid around my tongue, exploring its flavors. Per instruction, I gurgle. My mouth explodes, the alcohol transforming into a liquid fireball that burns the insides of my cheeks. It takes a few minutes before the sensation expires.

There is a saying: "para todo mal, mezcal, y para todo bien también."

For everything bad, mezcal, and for everything good too.

In Oaxaca, mezcal is as much a part of the landscape as the mountains, textiles and colonial architecture. Legend has it that a form of the tequila-like liquor existed prior to the Spanish conquest of Mexico, but mezcal as we know it was first distilled by the conquistadors in the 17th century. It is a generic name for spirits distilled from the agave plant, or maguey as it is traditionally called, of which there are 11 types. The state of Oaxaca is the traditional home of mezcal, and the countryside is littered with small family distilleries.

But not all mezcal is created equal. There is a difference between artisanal mezcal and the touristy stuff sold in bodegas across the city. I learned the difference at the Mezcaloteca, a tasting library run by a group dedicated to the preservation of traditional mezcal production.

Now try saying that five times fast.

This Photo of the Day, from Instagram user terra_tripper, features a golden Buddha statue nestled in the sands of Sanur, Bali.

Ostensibly, he's there to imbue the beach with peace and zen. We just think it makes for a cool picture.
