Some people really love the outdoors; others love sleeping on an elevated bed. What if there was a sport that combined these two things? Okay, sleeping hundreds of feet above the ground may seem a little extreme, but it's also fun, which (in theory) makes up for it. The International Highline Meeting festival even has a kitchen and bar for you to enjoy while 'chilling' hundreds of feet up. Maybe think twice if you're known to move around in your sleep though.
