Alright here's the deal. I'm mormon, I go to BYU. But seriously I don't judge anyone on NS for the typical mormon hate, or for what they think about mormons, I can respect people's opinions it's totally cool.
So BYU is definitely a mormon school, but most of the rumors are false that really affect daily life. You aren't supposed to have sex before you're married or drink, but pretty much anything else is game. Those are the only things that directly affect me, but it's part of the religion too so it's not new to me.
I'm 45 minutes from Park City, driving pretty fast. I've gotten there in 35 driving way fast. This more than an hour business? Not true. There are for sure some cool people here, but at the same time, there are some weirdos and some crazy mormons. If I wasn't mormon, I would go somewhere else, but I honestly like going to school here cause I'm mormon. There are so so so many super attractive girls here, and BYU is ranked really high on the educational prestige scale. It's pretty tough to get in and classes are tough as well.
And I don't know how many of you are around mormons that much, but it's the same as anyone else, the normal people who are mormons are normal people, and the crazy people who are mormons are crazy people. If OPs friend wants to go to BYU and he knows how it's gonna be and he's ok with it, he'd probably like it.
And there's good access to skiing. Basically the only place better situated is the U/Westminster.
