The Folsom Street Fair (FSF) is an annual
and leather subculture street fair held on the last Sunday in September and caps
"Leather Pride Week". The Folsom Street Fair, sometimes simply referred to as "Folsom", takes place on Folsom Street between 7th and 12th Streets, in San Francisco's
South of Market
The event started in 1984 and is California's third largest spectator event and the world's largest leather event and showcase for BDSM products and culture. It has grown as a non-profit charity, and local and national non-profits benefit with all donations at the gates going to charity groups as well as numerous fundraising schemes within the festival including games, beverage booths and even spanking for donations to capitalize on the adult-themed exhibitionism.
