Since you didn't ask, I'll throw it out there. St. George is very much a Mormon community. Unless you have lived in UT, it is suprising how deep the Church of UT has its fingers in everything in a community. We had some very active friends that retired early and found St. George to be a fairly inexpesive place to live with great weather, they moved after a few years because of the church's influence.
I have only spent a few long weekends down there and always found it to be a nice place to visit, but I wouldn't want to live there.
If you are aprt of the church I couldn't imagine a much better place to live, if not, I think you would be suprprised after 6 months or so how dominating the church is in the state.
In my short 40-something years I have lived in MN, CA, NM, TX, CO, and UT. Utah was the only place that I have ever felt a church's presence.
