7 hours? I'd stay in the airport huddled in a corner somewhere. I HATE commercial air travel.... mostly dealing with the airports and.. well.. people.
Factor in the time it will take to get out and back in (including going through security again) you cut the free time down to what?.... 45 minutes?![]()
This will be next Wednesday and if the weather is nice I'd like to do some sight seeing. Last year I saw Arlington and one of the Smithsonian museums.
