Surprising to me is Idaho. Reasons for leaving: bad weather and bad schools.
Bad weather: Eastern Idaho which is cold and windy. Most of the population lives in the "banana belt of Idaho" around Boise.
Bad schools: Nampa School District is awful. Other public schools are influenced by the LDS Church. The LDS Church and social network is a factor that almost everyone knows exists but rarely mentions directly.
I'd move back to Alaska if I could.
