Yes it's the Mormons bashing Mormons thread!
My LDS parents won't move to Utah. Reason..."Too many Mormons", says my Dad.
Mormons, or "Jack" Mormons?
What happens is too many people there get too complacent and just like with most places it has a 'small town mentality'.
Not knocking small towns, but if you live next door to Jim for 20 years and you know everyone in town... if someone new moves in, it can appear that it is somewhat of a good old boy system.
That being said, I figured I would have hated Utah and on some fronts yes, but on other fronts I had a really great time there.
First off I have learned to despise snow. If I ever shovel another spoonful of the stuff it will be too soon. None the less though I went in to Utah completely biased against the place but I ended up having a great time overall.
In the summer there is some awesome things to do if you are an outdoors person and yes, most people are very very nice.
Sometimes though even being nice turns people off. It comes across sometimes as too leave it to beaver, especially to those who want to remain a little rough around the edges. If you laugh at jokes with too much profanity in them (IE Chris Rock, Dave Chappelle, etc) you might not fit in to well in Utah.
