A bit of pain and pleasure… all for a good cause.

Traffic turned to gridlock in San Francisco’s South of Market District Sunday, September 28.

Thirteen City blocks were closed for the 26th annual Folsom Street Fair.

With nearly 250 vendors and two live stages, Folsom is the world’s largest leather-fetish event.

Proceeds raised benefit over a dozen charities.

Last year’s event collected over $340,000.

Over 400,000 people attend the fair each year.
