San Francisco is famous for being one of the worlds most liberal cities and also the gay capital, despite the fact that I met a guy that had no idea of this. I told him he should do a bit of background check before going on vacation next time.
It is the only city that I know of that twice a year arranges a leather and fetisch festival on the streets. Sure, in a sealed off area of course, but still.
Me, Peter and Sabrina went there together with the entire gay and fetisch community that seem to think that the usual Pride-parade is too boring.
