We did fly to DCA. Unfortunately (?) Delta is in the new terminal, which is nice, so there's no history there. I have wandered around the old terminal while in DC many years ago (pre-Val) and remember it being really interesting.
Have an awesome trip!!! I sure wish I could have signed on to go with you!
SIGH!
I'll live vicariously through your travel diary - much like I do with Pete's travels!
I have the QC15. If yours should happen to break they upgraded mine from the QC2 for $100. The new ones are even better than my old ones and I loved them!!!
