Boulder is creepy. I have a family member who is a police officer in Denver, and I go out occasionally to visit her - and hear stories about the well-off Boulder moms and dads who refuse to come down to Denver to pick up their stoned 14 yr olds who have been arrested while brawling/shoplifting/soliciting on the streets of Denver at 2:00 a.m. I think Boulder is a very weird culture - liberalism carried to its ultimate extreme.
I visited CO for the first time in July. It seems that, like Florida, Colorado is a land of both great darkness and great light.
