If you like leather, body hair, and a healthy dose of filth, then the Up Your Alley Street Fair is for you. This all-day event starts in front of the Powerhouse Bar on Dore Alley and stretches all the way to 10th Street. A precursor to the more famous Folsom Street Fair, Up Your Alley is a summer festival targeted to fetish enthusiasts and fans of BDSM with more than 50 adult vendors and close to 15,000 participants every year.
