Road tripping from SW to PNW. Need surplus stop recommendations.

Last month I road tripped to GA and stopped at CMP south and got an Eddystone. This month I need to go up to Seattle area from Phoenix and would love some recommendations for some sweet surplus stops along the way to break the monotony of the drive. I'll be headed up through Nevada, Idaho, and eastern Oregon.

I probably won't be buying anything in states like Washington but wouldn't mind checking something cool out.
