Folsom Street Fair is an outdoor event in San Francisco. It's an annual thing and is probably the largest leather/BDSM event in the country. It includes parades, tents, displays, parties, vendors, and lots of interesting sights I'm sure they have a website you could find from google if you wanted, though I don't want to link here to a non-sponsor BDSM-related site
Wow! It sound like a lot of very good open and broad-minded fun!
Well, no, I can't and won't be there but, please, if you take any pics can you post them here and tell us all about it?
