Warning: Mild hyperbole switch ENGAGED.
The whole Mormons control the state thing... no. We dont. If we did Rocky Anderson wouldn't be the Mayor of SLC. So give that noise a rest.
Oh, yes you do
Trust me, if you aren't a member of the local Theocracy you WILL feel like an outsider. Mormons, who constitute about 70% of the state population, are decent and nice folk as a group, but if you aren't one you will soon learn that you are socially shunned for the most part. I would imagine being self-employed in a service industry here would be a real bitch for a non member. 'Nuff said.
On the other hand, having moved to SLC from Los Angeles (job transfer) I'm simply amazed to see all the "noisy liberal crowded polluted traffic-infested left leaning" comments about sleepy little Salt Lake City. I live 20 miles from where I work, it takes me about 16 minutes to get to said work place. Houses are 1/4th the price of what I am used to. Everything's cheaper, food, gas, everything. On the other hand, local fashions are about 7 years behind the curve...and oddly enough the place is full of crystal meth addicts. It's apparently one of the nation's top Meth Lab locations. There's a bit of gang activity in West Valley but nothing that would ever make the news in a larger city.
It's true, local drivers absolutely suck. I think the "fog a mirror" test must be used by the local DMV. I have also found that in general the local schools turn out semi-literate individuals far too often. Finding really good workers can be a challenge.
As for culture and cuisine: alas, the local idea of Italian (often pronounced locally as "eye-talian")
and Chinese food runs to Olive Garden and PF Chang's, respectively, and this is STILL the only place where I have heard a person in a business meeting refer to black people as "darkies" and MEAN IT, but if you look hard enough you can find enough to keep you occupied, and flights to civilization are cheap, as it's a Delta and JetBlue hub.
Skiing and hiking are world class.
SLC and the environs are a great place to exercise your Second Amendment rights. The immediate area offers an IDPA or USPSA match every single weekend for the most part, with other competition opportunities to be found mid week evenings in the Provo ("Happy Valley") area. Better yet these matches are full of friendly fellow shooters who will make you feel welcome, especially in the IDPA matches.
State CCW laws are the least restrictive I have personally experienced, better than in Arizona. Gun and accessory selection isn't wonderful in the local shops, but prices are OK and some comments above will lead you to some of the brighter spots to shop. In SLC proper are two outdoor ranges, an excellent one called the Lee Kay center which is run by the state DNR, and a club at Holliday which costs only fifty bucks a year to join. Yes there is the odd yahoo in places such as Totally Awesome (to be avoided like SARS, IMHO) but places such as Rangemasters more than make up for it.
I'm also a very satisfied Impact tactical customer.
