Hours after the SCOTUS ruled on DOMA and Prop 8 on Wednesday, effectively making gay marriage legal in the state of California, San Francisco erupted into a giant, well-deserved party. The Supreme Court's ruling that the Defense of Marriage Act is unconstitutional and that Judge Vaughn Walker's original ruling in Prop 8 stands inspired hordes of people, gay and straight, to celebrate in the Castro, ground zero for gay rights.

Chief Justice John Roberts wrote the majority opinion on this one, which you can read in full here, and he was joined by Justices Scalia, Ginsberg, Breyer, and Kagan. When decision was revealed, San Francisco Mayor Ed Lee announced to hundreds of people at the City Hall Rotunda, "Welcome to the people's house! This is a historic day for all of us ... We have struggled for many, many years. I want to thank all of you for sharing this moment. Gosh, it feels good to have love triumph over ignorance, equality triumph over discrimination."

Wednesday's ruling comes just in time. This weekend the annual San Francisco Gay Pride Parade takes the city by storm. Hundreds of thousands of people are expected to show up this week to take part in the fabulous festivities.

Meanwhile, in New York City celebrations unfurled outside the Stonewall Inn, where riots in 1969 jumpstarted the gay rights movement.
