as of late the party scene at the U has gotten exponentially better. probably because of the desert parties. The girls have also become significantly hotter and way more fun to hang out with in the last year alone.
the only thing Utah really needs to catch up with boulder is a legit music scene and getting the mor(m)ons to fix the ridiculous alcohol laws.
Boulder is sick as fuck because you have the fox, boulder theater, multiple epic venues in denver and of course Red Rocks up in morrison. The smorgeshbord of music available in colorado kicks ass. You can see a dank bluegrass show one night, get your face stolen by jamband another, and then rave your ass off the next night if your wallet and brain can take it (in no particular order).
but i digress. In SLC you live 30 min away from the shred and still go to school full time. it's a real toss up. I have a twin brother he went to boulder and I went to the U. both are fun places to be and youd have to spend a week at each without your parents to make a solid decision.
