What do you see for me and my family centering around a possible move to Utah?
I think you will go, but I do not think you will love it there. Therefore I do not think you will stay longer than around 5 years. You won't hate it. I don't think anyone will be miserable. But it just won't completely vibe with you and your family. That doesn't mean the experience of it won't be nice for the time you are there.
