There's a wonderful sense of pattern and repetition in today's photo by Flickr user don.wright. Shot at a dance ceremony in Banda Aceh, the largest city on the Indonesian island of Sumatra, the photo's subjects each carry a unique expression that adds personality and charm. Some break into a bashful smile, some are expressionless, some – like the woman in the center of the frame – look deep in thought. I wonder what they're all thinking?

Taken any great photos during your own travels? Why not add them to our Gadling group on Flickr? We might just pick one of yours as our Photo of the Day.

Sometimes, having a delayed flight isn't such a bad thing, at least not for passengers aboard a recent Air Canada flight from Toronto to Frankfurt. Luckily for them, the Canada-based Lemon Bucket Orkestra were on the flight, and able to provide some free, impromptu musical entertainment.

According to USA Today, the group is a self-proclaimed "Balkan-Klezmer-Gypsy-Party-Punk Super-Band."

"Our plane got delayed 20 minutes so we got out the instruments," the band explains on their YouTube page.

You can check out the live performance above. What do you think?

While most travelers spend time visiting sites like churches, castles, parks and museums, Ichihara City in the Chiba Prefecture of Japan is hoping to bring in tourists with a new kind of attraction: the world's largest toilet. In fact, they're so hopeful that the unusual attraction will bring in travelers; they've spent 10 million yen (about $125,945) on the project.

The site, which sits in front of Itabu Station on the Kominato Railway Line, is actually your average-sized toilet; however, it's housed in a giant clear box and sits on an expansive 2,153 square-foot plot of land. While it doesn't provide much privacy on the property, there is a surrounding fence to hide the toilet from outsiders. The city is hoping the beautiful new toilet will provide an enjoyable reprieve for drivers and passengers of the train, as well as attendees of next year's Ichihara Art Festival.

Right now, the lavish restroom is only open to women, although the designer of the toilet, Sou Fujimoto, wants it to be open to the public for everyone to enjoy.

"I could enjoy the spectacular view while still feeling protected," the architect told the Japan Times. "No other toilet would allow you a feeling like that."

I met up with a childhood best friend of mine a few years ago in Boston. From there we drove to an ocean-side, dog-friendly resort in Maine that we'd decided to vacation at for a few days. Before we began our drive back to Boston, we realized we had all day to kill, so we chose our route back accordingly. Highway 1 isn't just a West Coast thing – it's pretty great on the East Coast, too. We took US 1A alongside the Atlantic Ocean down from Maine and through New Hampshire and Massachusetts. At different points in time, 1A connects with US Route 1. The names change along the way – in New Hampshire, it's technically called NH Route 1A – but the direction is clear: follow the road that runs alongside the ocean at every given opportunity. What would have been an under 3-hour trip for us on the highway from Maine to Boston wound up taking nearly 7 hours on these small roads, but it was all for a good cause: gorgeous scenery.

And from the, "OMFG" department comes this information, via press release: The American Association for Nude Recreation (AANR) "encourages wholesome family nude recreation ["Nakations"] in appropriate settings such as designated nude beaches and AANR-member resorts, or around the home. Experts have attested that children raised in a social nudist environment grow up with a stronger sense of self-esteem, free of many of the body image issues that trouble the average textile youth."

I'm most disturbed by the terms, "textile youth" and "Nakation." I'm not going to touch those with a ten-foot...never mind. Why I'm so skeeved out by the naked family vacay thing is a bit more convoluted. I like to think that I'm pretty open-minded, and it's true we've become a nation of body dysmorphic, eating-disordered freaks...when we're not morbidly obese, that is.

I have no problem going topless on European beaches, and have often bemoaned the puritanical leanings of Americans when it comes to censorship with regard to nudity on television and in magazines. I just feel that it's potential fodder for a therapist's couch when children and their parents frolic about sans textiles after the toddler stage has passed; I also believe that public nudity past toddler-hood is something that should only be done by consenting adults.

I've been to a nude beach twice. Maybe it's because I didn't holiday in the buff with my family (my eyes, my eyes!) as a child, but I can tell you two things my nude sunbathing didn't accomplish: providing me with a stronger sense of self-esteem, and freeing me of the body image issues that have troubled me ever since I was an average, deprived textiled youth.

During hotel renovations last August at the Sofitel Legend Metropole Hanoi in Vietnam, construction workers discovered an unknown bunker thought to be used during the Vietnam War. While drilling near the poolside bar, they found a flooded hallway, numerous rooms and a staircase leading to the secret 500-square-foot bunker. Moreover, wine bottles, unbroken light bulbs, graffiti and air ducts were also found, according to VietNamNet.

"In the hotel's history, there is a story of the American folk singer, Joan Baez, who sought shelter in this bunker during the Christmas Bombings in 1972, and who sang some songs beside a Vietnamese guitarist," explains Kai Speth, the hotel's General Director. "We don't know of any other hotels, in Vietnam or anywhere else for that matter, that maintained a shelter for guests and staff."

The luxury hotel is the oldest in Hanoi, boasting a 110-year history that has welcomed guests such as Charlie Chaplin, Jane Fonda, Fidel Castro and Somerset Maugham. That will be celebrated, along with the opening of the bunker to guests, on May 21, 2012. Likewise, people who actually spent time in the bunker, such as Bob Devereaux, the Australian diplomat who carved his name into the bunker in 1975, will also be present at the opening ceremony.

Mark Adams is the author of "Turn Right at Machu Picchu, Rediscovering the Lost City One Step at a Time," his bestselling account of his attempt to retrace Hiram Bingham's groundbreaking 1911 expedition to "discover" Machu Picchu. The book, which is now out in paperback, was a New York Times Bestseller and was named one of the best non-fiction titles of the year by Men's Journal and the Washington Post. Adams gave us the inside story of what motivated him to take this expedition, shared some tips on visiting Machu Picchu and gave us his take on Bingham's legacy.

What inspired you to trace Hiram Bingham's famous Machu Picchu expedition route of 1911?

I was an editor at National Geographic Adventure magazine and working at a place like that, Machu Picchu played the same kind of role there that Tiger Woods might have, pre-scandal at Golf Digest. It's always in your face; you're always thinking about it; you're always trying to come up with new ways to look at Machu Picchu because people love it. They can't get enough of it.

Why is that, do you think?

It has that little element of mystery. Someone once said that you can't take a bad picture of Machu Picchu, and I think it's that iconic shot that's just so alluring that people are really drawn to it. People think, 'That's one of those places I want to see before I die.' It's so far out and it's so exotic and yet, pretty much anyone can do it if they have enough money and time.

Are you still making plans for Memorial Day weekend? Then look no further than Mammoth Mountain Resort, where unique spring weather conditions have made it possible for visitors to ski, mountain bike and play golf all on the same day.

Even though the Memorial Day weekend often marks the unofficial start to summer, Mammoth isn't quite ready to completely give up on winter just yet. The resort is one of the few places in the U.S. where it is still possible to ski this spring and the lifts will remain open from 7:30 a.m. to 2 p.m. through Monday, May 28.

Once you've finished taking a few turns on the slopes, head over to Mammoth's fantastic mountain bike park, which officially opens for the season on Saturday, May 26. The lower-mountain trails will be fully accessible and the uphill shuttle will run from 9 a.m. to 5:30 p.m., making it as easy as possible to bomb down the great trails there.

Finally, cap off the day with a round of golf on the Sierra Star Golf Course, which opened for the season this past Friday. The beautiful course is surrounded by snow capped peaks and is also located at 8000 feet above sea level, making it the highest course all of California. The thin air will add distance to your drives while the serene setting will brighten your mood, even after a three-putt.

Because it is so unusual to be able to ski, mountain bike and golf all on the same day, Mammoth is offering fantastic deals on passes for the weekend. Visitors can choose to either ski and ride or ski and golf for just $79 or they can elect to partake in all three activities for just $99. That seems like a bargain for a very active day outside. Check out all of these deals and more on the Mammoth Summer Kick-off page.

This Photo of the Day was taken in Monument Valley, Utah, and comes from Gadling Flickr pool member oilfighter. It is titled "Drama Over Cowboy Land."

"I've been to Monument Valley a few times, but the sky was usually cloudless," says oilfighter. "Boy, what a sunset. The clouds broke, and the wind sent them flying. The last light of the day gave the sky a pastel pink hue."

Upload your best shots to the Gadling Group Pool on Flickr. Several times a week we choose our favorite images from the pool as Photos of the Day.

Tips for getting featured: in your Flickr account check "Privacy and Permissions," and check "yes" on "Allow others to share your stuff." Adding information about your image does not hurt your chances either.

Along with "Drama Over Cowboy Land," oilfighter tells us, "I used a 2 stop graduated ND filter to balance the exposure, and thus bring out the colors in the clouds. What a beauty!"

On the night of June 28, 2012, Singapore will debut its brand new Gardens by the Bay, which has been under construction for the past five years. The attraction is the first of its kind in Singapore. The launch takes place in the city's new Marina Bay downtown area, and is part of the "city in a garden vision," which aims to make Singapore a place of natural beauty.

From June 29 to July 8, to help celebrate the 134-acre garden's grand opening, there will be concerts by Jason Mraz and Corrinne May, family carnivals, an eco-friendly green fair, trail hikes, movies under the stars, live entertainment, a photography competition, storytelling, educational demonstrations, children's activities and more.

Gardens by the Bay will feature many different facets. Visitors can choose to wander through the cooled conservatories of the Flower Dome and Cloud Forest, stroll through the Supertrees in the Golden Garden, learn about Singapore's plant history in the Heritage Gardens, discover aquatic life in the Dragonfly and Kingfisher Lakes and educate themselves on an array of flora in the World of Plants. And for some extra excitement, there will be choreographed light and sound shows in the Supertree Grove, changing floral displays in the Flower Dome and interpretive media performances to bring the story of plants to life.

Gardens by the Bay will be free to enter, and will be open to the public from 5:00 a.m. to 2:00 p.m. daily.
