Just a heads-up I'll be in the area from tonight (17th) through Sunday.
Sounds like GoingAway and I will be possibly meeting up tonight, but plans aren't firm. (Not sure what time I'll be arriving as I'm driving down after finishing up some things this afternoon.)
No concrete plans for Saturday except wandering aimlessly and catching up on being a tourist in DC. Sunday I may be occupied but specifics aren't yet confirmed.
