SoMA in San Francisco has been a hub for the leather community for decades. So it’s not too surprising the area south of Market Street  hosts not one annual leather street fair, but two.

The legendary Folsom Street Fair is in September, but the last weekend in July, nearby Dore Alley hosted Up Your Alley, offering street parties, leather accessories, BDSM demonstrations, porn stars and more. And this year the fun was spread out to several Folsom intersections—more room for naked Twister!
