Actually, we were thinking Montana this year. Perhaps Arizona in 2022, as next year we’re supposed to go to Peru.
If you do go to Montana, make sure you get up to the northwest corner, by Glacier Lake, Whitefish and Kalispell. Beautiful country, though you might not see any glaciers due to global warming.
The plan is 5-6 nights around Glacier NP. Whitefish is on the list for an evening, Kalispell is a maybe. Really, the only towns I had planned were Whitefish, Bozeman and Deadwood SD, otherwise other towns won’t get much more than a brief stop. It’s a camping trip.
Theodore Roosevelt NP
Missouri Breaks
Glacier NP
Bozeman with a brief trip to Yellowstone NP
Black Hills SD including Mt Rushmore for my Peruvian, Deadwood, maybe Jewel Cave
Badlands NP
