The National Museum of the United States Air force.
Located on a portion of Wright Patterson Air Force Base, Dayton, OH - this museum is maybe 30 miles away from my home.
I rode the Burgman 400 there Saturday...with my family following in the car. (the museum has a well looked after cycle parking area)
This museum is open to the public, admission is free, it is clean & well supervised. The staff are friendly and informative. There are a couple of lunch counter areas, and quite a few places to sit down - which is handy now that they've recently opened the 4th huge hanger full of planes.
That 4th hanger houses a few presidential planes, (Roosevelt, Truman, Ike) including the one which took Kennedy to Dallas, and back .... - all of which you can walk through.
(Roosevelt's plane has an elevator cut in the plane's belly to board him in his wheel chair.)
After going through security there is a large gift shop...
Bing up pictures of the museum. The scope of what is on display in this museum is amazing. We paid for the hardware on display - donations paid for the museum.
I've been there maybe 75 times over the past 35 yrs, as a hospital tour director and as a citizen. It never fails to impress me or teach me something. If you had a week, you might see & read it all.
