Back when I was in my early twenties, me and a bunch of anarchy inspired dancers made up some fake letter head that said, "Community Health Study Group." On the letter head we wrote to the San Francisco Police Department asking for a permit to parade through the Financial District. The letters said, "We are planning an educational procession to draw attention to the contemporary and traditional medicinal uses of clay on the skin." They gave us the permit and a police escort. After collecting about twenty buckets of high quality mud from a nearby ocean side open space, about 40 of us gathered in a park on the edge of the Financial District and started to cover our bodies in mud. We made two rules before starting.
