I'm thinking of moving to Boulder, CO for my last 2 years of college. Any thoughts or advice on living there?

I've lived in all my life, and am looking for a change. I'm a vegetarian and I'm very into animal rights. As far as athletics goes, I know Boulder is a very active town, and I'm not very athletic. Does anyone have any thoughts on the University of Colorado in Boulder? Or any thoughts on living in Boulder in general?
