I have been in Pocatello when it would freeze a turd in a dead Eskimo — more than once.
Born in Idaho Falls, raised in Pocatello from age 10 to 18. Left when I joined USAF in '59, discovered warm climate in California and Spain, and never for a minute wanted to go back (except for a visit).
Pocatello is cold in winter with more than enough snow, hot (as hell, frequently) in summer.
Visit, look around, your choice. Mine was easy. Hope yours is also.
