I have been to Wright-Patterson, very nice.
I was at Seattle, must have been when they first opened it up. . .it was pretty bare.
Pensacola is a good place for not only US Navy, but US Coast Guard as well (I helped restore the USCG HH52A on display)
But, by far the best I have seen was in Cadillac Michigan. . .not a museum but a WWII fly in! A B17G, a B24J, a P47, a P51, a Spitfire, 10 SNJ's with various "make up" Best of all, you were allowed to view each aircraft up close and go inside the B17 and B24 with NO FEE!
ANGB Selfridge (MI) has a fly in airshow every other year with lots of aircraft of all eras that must fly in to participate, one exception was an Me109G being restored.

I know it's only rock and roll, but I like it.
