I'm going to my local Apple Store (Clarendon) tomorrow morning. Planning on getting there before the store opens and wait outside.
I went to the same one on the second day last year to get my 4S, but around noon, and they had just got a shipment in the day of the release but had saved it for Saturday & Sunday sales.
I'm really hoping they'll do the same this year, if they get another shipment...
If not, then there are tons of other Apple Stores here in the DC area, one is bound to have the one I want.
