Fort Collins, CO - Beautiful city, with a fun college atmosphere. Everything you could want is within an hour or two's drive...Denver, mountains, skiing...all right there. It reminds me of a midwest town that got up and moved near the mountains. I'd love to live there someday.
1. Boulder is 5 times the city Ft. Collins is it is much more scenic and has a better college atmosphere. You should go check it out because if you like Ft. Collins, you will love Boulder. And with Boulder you are closer to Denver, the mountains and skiing. However, you do have to ignore the homeless, hippies, and self righteous liberals with ski racks on their prius. If that bothers you just stick with Ft. Collins
2. If you are going to talk up Ft. Collins please include the fantastic breweries housed there. Odells, New Belgium, Fort Collins, Coopersmith and the fact that you can check out a bike at the bike library and ride to each of them.
