It was a lusty, warm day at Folsom Street Fair yesterday, and people showed up in droves to show themselves off in their leather harnesses, bustiers, jockstraps and the like. They also showed up in droves to gawk at those who chose to dress up, and to enjoy some overpriced beer on what might well be the last summery day we'll ever know here in SF. Please enjoy this gallery of photos by Darwin Bell and Joey DeRuy. See even more (many of them NSFW) at Le Fag.

You may not be into leather or the BDSM scene, but if you live in San Francisco you've probably breezed through Folsom Street Fair once or twice. Call it what you will, but it is the largest event of its kind in the world, and the third largest single-day outdoor event in California -- behind SF Gay Pride and maybe Long Beach Pride? (We think these numbers are hard to nail down, but suffice it to say the gays like to party outdoors.)

Courtesy of NSFW gay blog Le Fag, we have this roundup of events both social and cultural happening in conjunction with Leather Week and Folsom Street Fair weekend. Cheers. And remember, this SF... no judgment.

Amdist threats of a crackdown on fun (and nudity, and lewd behavior), the fetishy gays and their fetishy friends gathered under an unseasonably warm sun on Folsom Street on Sunday for the annual Up Your Alley fair. It could be described as a dirtier, and gayer Folsom Street Fair, and this year's fair was no less dirty, and no less naked. But to the SFPD's credit, with the large crowd that gathered (estimated at 12,000), it was a lot harder to spot the exposed genitalia until it was too late. Here are a few pictures (several NSFW!), including a shot of our beloved State Assemblyman Tom Ammiano Senator Mark Leno in conversation with friends while wearing his trusty leather pants.

UPDATE: Our deepest apologies for mis-identifying Mark Leno as Tom Ammiano. Blame our drunk friend who pointed him out to us. Tom wrote in just to say, "That's Mark not me, it's safe to say that I've never been in Mark Leno's pants."
