This is a fabulous museum that is too little known. Although it took us about 1 hr 45 min to get there from Vancouver, WA, it was well worth it (at least a 15-20 min construction delay on I84 East).
They have 3 hangars PACKED with exquisitely restored airplanes, cars, and motorcycles. It is a "living" museum, with every item capable of being operated, which they do on a rotating basis.
We ran out of leg and back power before we got to everything (we're 74 and 77 years old). They have electric scooters you can rent if you need augmented motive capability.
Excellent, short, meaningful videos are interspersed throughout. They even have places to sit and rest while enjoying exhibits.
I'll be going back for sure. You really need to experience this place first-hand. GO! Admission is $25 ($21 for 65+). WELL WORTH IT!
