According to the AP, Philadelphia's annual Naked Bike Ride is moving from September to August.  Organizers say the change is due to the fact that the weather during the last two rides has been "chilly."

PhillyVoice.com says that, "Thousands of cyclists that wear little-to-no clothing, glitter, costumes, and body paint turn out every year to advocate for safe streets and body positivity."  In addition, the site notes that last year, the day before the ride was "dubbed Bodypainting Day so cyclists could get professionally painted for the ride."

According to the event's Facebook page, the ride, which started in 2009, is used "to promote fuel conscious consumption, positive body image, and cycling advocacy."

Last year's ride started at Glendinning Rock Garden and ended at Love Park.
