Utah Mormons are of a different mindset, they're on home turf in their promised land and they act like it.

There's a Mormon that runs a local business in my area. One day he puts his business up for sale because he wants to move to Utah to get closer to his faith. Ends up moving back and reopening a couple of years later -- turns out he was Mormon, but not Mormon enough. They don't like outsiders, not even the Mormons from out of state, which kind of makes sense with being a historically polygamous group which expels the young men who aren't in the "in" group. Breeds a mindset of exclusivity.
