Yes, I can't post nudity here. Go to my gallery to see the uncensored images. In all, I'd say 10% of the riders were totally nude, 80% rode topless, and another 10% wore full-clothing. This was the first-ever event of it's kind held in Philadelphia, so most of the riders were being cautious because no one was sure what was going to happen with the PD. As it turns out, the Philly PD were extremely helpful and even escorted the ride in the busiest parts of the city (ie around City Hall, Rittenhouse Square, and the Art Museum).
The 2nd Annual event is already planned for next year. I'm sure it will be bigger with more 100% nudity.
