Each year, on the last Sunday of July, on Dore Alley between Howard and Folsom in San Francisco, approximately 15,000 men come together to take part in America’s “Dirtiest Festival.”

"Up Your Alley," aka "Dore Alley," caters to leather daddies, bikers, punks, skinheads, twinks, bears, rubber and latex fetishists, queens, pups, furries, jocks, and on.


As even their website confesses,

"It is not for the faint of heart."
