Falcon Field in Mesa has a small CAF museum.

Skip up to McCLellan AFB (former) to see the Aerospace Museum of California,and to Castle AFB for the Castle Air Museum.
Afton, Wyoming has the Aviat factory; they're always friendly.

Evergreen has a big display, including the Spruce Goose in their museum at McMinnville, OR.
Denver has the Wings over the Rockies museum.
