...but the U of U LDSSA & LDS Frats/Sororities are very good, and thereby make for a good LDS experience away from a place like BYU (in my own experience). I've taken institute courses from Stephen E. Robinson, and I would assume the faculty up there is still of a high quality.
Away from BYU/UVU, you're always going to deal with some level of anti-Mormon sentiment, and it's a little magnified because of the rivalry...but I'm sure your kids would be able to overcome it if they (gasp), had to go to the U.
