Apologies if I missed some previous threads on this subject. I will be flying out of DCA 10/21 and will be dropped off early at the airport, so I have about 4 to maybe 5 hours free to see some sites. I won't have a car or any other transportation besides the Metro. I was in the same situation a year ago and saw some of the Smithsonian facilities.

I certainly wouldn't mind doing that again, but can any FT'ers suggest other places on the Metro that I could see in that short time frame? I would appreciate anyone's ideas.

Thanks!
Dan
