Nope, but I'll most likely go to the one in Baltimore, though it is tempting to go down to DC that day, check things out for a bit, maybe take in some museums. So I guess that should be maybe.
I plan to park at New Carolton and take the Metro in. No way am I going to attempt finding a place to park in that mess. I was actually thinking about a room in the city for the night since there is so much going on that whole weekend.
