Correct.
I would rather go to UC Berkeley, join the ski tea, and go 2-4 weekends a month. You won't ski 80 days a year, but you might get 40+. You can take a semester off at some point and just ski, and you can ski bum for a couple of year (maybe forever) when you graduate. Going to a solid school is the way to go.
I don't know anything about Sierra Nevada, or CMC, so I'm not putting those places down, just agreeing with the first part of the poster's statement.
You don't want to make decisions now which limit you in the future. You also don't want to completely give up the things you love. I went to school 5.5 hours from Mammoth and still skied 30+ days a year. I took a winter off, and ski bummed for a few years after school. Keep your options open.
U of Utah and Boulder seem to be good options. If you go to Boulder, make sure you balance the study/party/ski equation. That being said, the fact that you have to balance it makes it somewhere you might want to be. I would not want to go somewhere with no social life and no outdoor life. Not for undergrad anyway.
