For the Hermit Who Has Everything

Want some out of the way place where you and seven of your closest friends can just get away from the world for years at a time? Then step right up and put a bid in for Biosphere 2, the only scientific experiment to serve as the inspiration for a Pauly Shore movie. I don't recall what the experiment was supposed to prove, but it did show that being cooped up with seven other people in even a 3.1-acre building can send a person right of the deep-end.
