As many of you already know, Proposition 8 was upheld by the California Supreme Court (although the existing 18,000 same-sex marriages are allowed to stand). So the people at Day of Decision will be coordinating PROTESTS, not celebrations.
I walked over to Sheridan Square a few minutes ago (the site of the NYC Protest at 6:00 pm) and I noticed blue police barricades had been delivered, but not set up yet.
BTW - if you look closely at the picture above, you can see the famous George Segal sculptures - "Gay Liberation" in Christopher Park (on the right). The park is directly across the street from the Stonewall Inn, and this was where the Gays and Drag Queens held their ground and barraged the police with bricks, bottles, and even pennies on the night of the Stonewall Riots.
