I've lived in both places (SLC, the Four Corners, SF, Menlo Park) and spent many weeks at a time in Delta, UT, in addition to places in New Mexico.

I'd love to live in Torrey and I'd move back to SLC if I could get a job in an industry that doesn't suck, but all things considered I'd take the bay area over anywhere in Utah.

I lived in Utah for three years and also loved the national parks and outdoor activities, but the culture (i.e. heavy Mormon influence) was pretty unbearable.
