We lived in the Idaho Falls area for the last 50 years. Love the economy, town, area in general , job opportunity I was provided, and amazing hunting and fishing. I would never try to steer people away from it.
People are the problem, and tend to be people, no matter where you go. Tho we are non Mormon, never had a problem with them in any way. I drink, they don't - more booze for me, and as long as the State has liquor stores, I'm good. If you don't like em, don't hang with them. Same goes for Dems, liberals, illegals, LGTBQ odd ones.
After 8 years of retirement, we moved. To the Boise area and Treasure valley, of all places!!! Just couldn't stand the winters and snow shoveling anymore. With 15 kids, grands, great-grands, and other family on the West side it made no sense to stay in eastern Idaho.
The answer, move. I hate Boise, traffic, people, 800K people in 3 cities and 200 square miles. The process is easy once you decide that close doesn't have to be bad. We bought a great house in a nice neighborhood, one mile from the lake and wildlife refuge, five miles from the dump, eight miles from an amazing county funded and run public shooting range!! I will die in 10-15 years and never regret the move. If I don't like stuff, I just won't do it!!
