I applied there for grad school in biology this past year. Got an interview, but didn't end up getting accepted. My interview weekend was awesome, haha. I went back country skiing at Alta the afternoon after some interviews and then got on the plane back home that night.
I think it would have been a cool place to go. Before getting rejected, I'd say I was deciding between there and UT-Austin. I kind of wanted something different from CU where I went for undergrad, so I was hesitant to live in SLC. The people I met were the coolest and most normal of all the graduate students I met though. I was worried that SLC wouldn't be a great place to live not being an undergrad, but I'm sure its fine. I'm here in Austin now, which I really like a lot but obviously skiing is out. I'm not really bummed I'm not there cause I think it would be too frustrating balancing the work/school requried in grad school with epic skiing days there. Such a distraction.
I'll take my occasional trips there and be satisfied.
