My thoughts on "good" vs "not very good":

I live in Saint George (very far Southern Utah). It's beautiful, the weather is great (if you like hot and dry), and Washington County is very small compared to Utah County and surrounding areas. Traffic is becoming something of a problem and the area is going to be under constant road construction for the next 20 years if growth continues.

There are very few software companies in the area: PrinterLogic, BusyBusy, Mango Voice, and perhaps a few others. If you do move to the area, make sure you have plenty of remote opportunities or are willing to commute to Las Vegas daily (about 90-ish minutes one way).

That's like correcting someone saying California has high salaries. "Well sure, maybe in th cities, but not on farms or in the mountains!"

Of course Capitol Reef, Zion, and a bunch of relatively small towns don't have good pay.
