SAN FRANCISCO (CBS SF) — Several streets are closed Sunday for the annual Folsom Street Fair in the South of Market area.

The following streets are closed until 10 p.m.: Folsom, between Eighth and 13th streets; Ninth, 10th, 11th and 12th streets, between Howard and Harrison; Dore, south of Howard; and all alleys and intersections between Eighth and 13th streets and between Howard and Harrison.

Muni will reroute the 9, 12 and 47 routes. The 19 may experience delays near the event area.

The fair is billed by Folsom Street Events as “the world’s biggest leather event … with 250,000 fetish enthusiasts spread over 13 city blocks.”

On Sunday, thousands of people participated in the fare, many wearing masks, leather and leashes. Some were even in cages. The annual festival celebrates sexual fetishes and has been held since the 1980’s.

The festival has grown to include people of all genders and sexualities. Different fetish communities came together to celebrate their interests.

“Folsom is amazing and I look to see the diversity and the different camaraderie of groups that come here,” said Bobby Lindsay, an attendee of the fair visiting from Denver.

The event was clothing optional.
