Partners Bill Wilson (R) and Fernando Orlandi walk inside San Francisco City Hall as they prepare to get married on the first full day of legal same-sex marriage in California June 17, 2008. California performed its first legally recognized same-sex weddings on Monday and opened its doors to gay and lesbian couples from around the country, a move likely to challenge other states that define marriage as between a man and a woman.
