Finally I get a chance to log on here and update you guys! :-D
To GoingAway, a BIG thank you - I did just that (called Red Top Cab) and made a reservation for a minivan. The driver came exactly on time (actually, about 5 minutes earlier) and the total charge came to $21 (plus $2 in tips). DEFINITELY not a bad deal, and the driver was friendly. I know how I'm going to get to DCA alternatively if metro is not available now in the future. Thanks! :-D
Now, I'm HOME. =)
Gre, hahaha, I don't even know you? :-P
