Thanks for all this knowledge and experience. You have expanded my area of interest and I will make efforts to see them all. I had written Idaho off as having too many Californians already. Most of them had made a lot more in the equity lotto than I will and so have probably snatched up the better places. But they may have different tastes than I do, so I will look around. I have not yet been to Idaho or Montana.
As for the Mormon community issue, I know that I will be the outsider moving into their area. I have had good luck with LDS kids coming by as missionaries. I am concerned as any parent would about the girls getting along and making friends. The renting idea is a sound one.
