It’s a little-known fact that the Folsom Street Fair itself is just one part of the weekend festivities, a sort of beer-guzzling, pot-smoking, semi-naked warm up for the real thing. This year there were at least a dozen wild public parties (sorry, our sponsors won’t allow us to take you inside any of the private ones!) on and around Folsom Street, and they were as full of hard-core debauchery as ever. We sent photographer Kevin Kauer to record some of R rated goings on around the cool, gray city of love. The following pics are from the parties Deviants and Hard French (starting at slide #7), both of which took place on Sunday afternoon after the the fair had faded into a hazy fog of memory.
