Questions about activism on Supreme Court oral argument day [View all]

I'm not that well informed, don't read enough in the gay press.

I was wondering if there are places I can go to find out about who is organizing demonstrations for the day the Supreme Court is hearing oral arguments on the California Prop 8 case next week.

Any media events scheduled? Are they all in DC or in other major cities, (Boston, NYC, SF, etc.)

Any resources I can check would be helpful. Thanks
