I live in Nampa, ID, which is about 30 minutes outside of Boise. I would highly recommend this state. There is plenty of land to choose from in the surrounding areas. Kuna, about 20 minutes from Boise, has a lot of acreage for horses. You're going to have a hard time finding a lot of acreage with a lot of greenery around here because it's mostly desert. However, if you work in Boise, it is beautiful. Boise is known as the City of Trees.
Sorry, but I can't help on the salary issue. I'm a student at the local university, so I'm not positive on any numbers.
I am quite confident in the public school system. I spent my entire education in private schools, but I've never heard anything horrible about the public schools. Boise has many great schools.
Hope this helps a little!

I'm interested in knowing about this also. We are considering a move to southwest Idaho, and I would like to have a decent house on some acreage. I like lots of trees and greenery.
