If you ever happen to visit Portland, Oregon, I strongly recommend heading down to the Evergreen Aviation Museum - seeing the Spruce Goose in person is just breathtaking.
I second this (though it’s in McMinnville, about an hour south of Portland). Quite a collection of aircraft and spacecraft. Next door you kids can go in a pool with a water slide that starts in a 747 on top of a building!
Plus your taxes paid for it (via a CIA front company)!
