i have only visited utah...but i can see some pro's and cons....i guess the first pro would be the commeradery, or how common LDS members are there, and as was stated earlier, the multitude of temples.......but as another mentioned briefly....i can't help but think that there is a con to what might be percieved as a kind of being sheltered from having to deal with life in an environment that was not so concentrated with members.....i believe the challenges are shaded a bit differently....but while i was there i did think it was a beautiful state
