The Formula Smack Pack race in Texas sounds a lot like the mountainbike singlespeed "competitions." Nurse's costumes on guys (over leathers), the women's winner didn't even ride, lemans start and major course-cutting without consequences, and it sounds like tons of fun, for charity even. Oh yeah, and they were on supermotard motorcycles -- tricked out single-cylinder dirt bikes set up for street riding. It's kind of the motorcycle equivalent of urban assault or singlespeed or something.
My friend sent me the link with the byline, "all they needed was a jump through fire." I can't believe they missed that.
