There's a lot of information out there about the World Naked Bike Ride. The best page is probably the FAQ page, which includes such important ones such as "Isn't riding naked uncomfortable," "Is it legal to be naked in public," "Won't it hurt my genitals," and the all-important "What if I'm not conventionally attractive?" Of course, most of the people riding in this aren't "conventionally attractive," as a quick glance at some of the photos at the site will attest. Brad Pitt and supermodels don't ride their bikes naked, people. You've been warned!
Perhaps not surprisingly, there are no naked rides near me (Arizona is fairly conservative). There's one in Eugene this weekend, however, so if you're in the Pacific Northwest, head there! Maybe there will be cute coeds! Probably not, though. I'm not sure why the only people who want to get naked in public probably shouldn't. This is known as "That Seinfeld episode on the train" phenomenon, when the fat dude stripped down on the way to Coney Island. Nobody wants to see that!
