San Francisco brings to mind different things to different people. The Knot cites San Francisco as one of the top contenders on its "Most Romantic U.S. Cities" list. Forbes.com gave San Francisco first place honors on its "Best Cities For Singles" list for 2007. But one thing the city has historically been known for is a vibrant and supportive community for gays and lesbians.

The City can lay claim to 37 years of celebrating lesbians, gays, bisexuals, and transgenders in an annual parade. The 37th Annual LGBT Pride Parade that took place during June 2007 drew hundreds of thousands of spectators — the attendees ranged from politicians like Mayor Gavin Newsom to big-name corporate sponsors like Google and Kaiser Permanente. It's only fitting, then, that San Francisco made its mark as the city on the forefront of legalizing same-sex marriages in California.
