@ajroach42 Used to live in that area -- if you have any interest in aerospace and haven't been to the big Smithsonian expo at Dulles Airport, it's worth a visit -- I liked it better than the main Smithsonian aerospace exhibit in DC.
Even people who aren't complete aerospace nerds like me seem to be in awe of it, while there. It's basically a gigantic hangar filled with entire airplanes, like the Concorde, the first passenger jet (boeing 707), etc.
