Great Report! Really enjoyed reading it.
I've seen a lot of the places you went through, From CA through Idaho and MT to the midwest. I grew up in Red Lodge, at the bottom of the Beartooth Pass but have not been back there in a while now. Makes me miss it! Also went to wall drug, rushmore, and the Corn Palace as a kid!
I really want to take a big ride throughout the west (I'm in WA now), I just have to make sure my old (Only) bike ('78 kz650) is up for it. A great bike, but still recovering from a couple decades of neglect from the PO's before I got it...
Anyway, Thanks for the great read!
