Having grown up in the Northern Rockies and spent about a year in Alaska I know what I can't take and it is humidity.
Humidity just kills me.
Lived a lot of hot places, and a lot of really cold places. I can manage the cold and heat, as long as it isn't humid.
I'd move to Casper, Wyoming if I was retired. Or Thermopolis, Wyoming if I wanted a small town with almost zero services.
Wyoming has no preference points for deer, elk, antelope, mountain goat and bison as a resident. Neither does Idaho or New Mexico. In Wyoming they have non-point draws for bighorns
Idaho is ok, but booming and prices are too high, New Mexico is pretty good. If you want some locations in New Mexico or Wyoming to check out let me know.
cheers,
Seth
