The 12th Annual "Celebrate America" Underwear Run took place Friday evening in Central Park. The "fun" run takes place every year on the Friday before the much more serious and competitive Aquaphor New York City Triathlon. Organizers encourage the 500 participants to dress as patriotically as possible. Many dressed like Captain America, two girls as Mt. Rushmore, others as the Statue of LIberty, and of course, the Naked Cowboy was this year's Grand Marshall.
