I paid for all my tuition, housing, skiing, everything last year at the U of U as a freshmen.  It was a good school, but I was lucky enough to have had a damn good job since 8th grade to be able aford to do all that and still get a business loan to start my own business this summer.  Im not going back to school since ive started my career that is perfect for me since its seasonal so I can ski haha.  But if I was to go back I would definitely go to the U of U again.  Moral of the story, get good at saving money in the summer if thats what you want to do.  Unlike CO schools, utah tuition is a lot more affordable and the mountains are close.  Montana State would be my second choice followed by Western Washington.  I have some friends at Western Washington and it sounds like a good school as well but its an hour from a ski moutain.  At the U of U the mountains are about 30mins away... like 6 different ones, hardest choice youll have if you go there is where to get a pass to.  There is a ski resort about 20 mins from MSU and another about an hour, Montana's out of state tuition is a lot more affordable than Colorado's as well.  
Everyones going to be biased towards their school.  I suggest looking into the schools that have the major you want, or if your undecided go to a big school with lots of options to choose from later.
