The original: San Francisco's leather and fetish street fair, and the biggest of its kind in the world.
Folsom Street Fair closes several blocks of SoMa on the last Sunday of September for the world's largest leather and fetish event. The fair itself is daytime and outdoors; the parties before and after — through the whole preceding week — are where the city's clubs go all-in.
Up Your Alley, its smaller sibling, lands in late July.
