Marriage Equity March on Washington: Self Organizing on Facebook?

The call for a marriage equity March on Washington seems to be picking up steam. There are already three Facebook networks planning a march and this page devoted to discussion the best time for it to occur.

My vote is mid-September. Any time before summer is too soon to organize well. But you want to do it before school gets going too much, but August is a terrible time to plan anything in DC. So September, I think. Though timing it in October for the 30th anniversary of the first March isn't a bad idea either.
