The World Naked Bike Ride, an international demonstration against fossil fuel dependence, was held in San Francisco this weekend, they cry "Less gas, more ass" and "put the fun between your legs." It was peacefully held despite the new law prohibiting nudity.
Their website warned participants: "To be legal, you just need to barely cover your genitals and rectum. Going naked outside the main group will definitely get you cited,". "This will be a test to see how far we can push the limits."
