You may add a comment on Boulder if you want. I have spent a good deal of time there and consider it one of the more beautiful cities and openly liberal. Boulder is a very cool city. Liberal and freindly. Denver, Boulder and Aspen were the three cities which had pro-gay ordinances in place when Amendment 2 was deceitfully passed.
Boulder is an extremely expensive place to buy real estate.
Fun Fun Fun town. Okay, I live in Denver, and have for more than a decade. Yes, it's fun. Yes, it's beautiful. And, yes, there is a certain sense of community.
