Went into sensory overload today!  We visited the Udvar-Hazy Center of the Smithsonian National Air and Space Museum today near Dulles airport in Chantilly, VA.  One HUGE hangar houses the Space Shuttle Discovery, SR-71 Blackbird, the Enola Gay, and an Air France Concorde along with 300 aircraft of every description.  I have never in my life seen such an exhibit of aircraft.  This even beats the EAA Airventure in Oshkosh, Wisconsin.
