Lived in Denver for 10 years. I loved Boulder, spent 4-6 days a week there. Used to bring my Afghan Hound to run at Chautauqua Park in the snow, he loved it(I never picked up his shit though). The Brewing Market was my favorite coffee house. Their Mountain Chai was very good. The Falafel King was great. Nick and Willie's pizza was outstanding. But...... I hated the spoiled, ultra whiner, naive, hypocritical, libby CU students, what a pain in the ass they were.
Also..... Red Rocks was the greatest place to see a concert.
When did you live in Boulder? I lived there in 2004-2005, and went to CU, the student body president was a Republican and so was most of the student government (which I didn't understand why the political spectrum was part of the student elections?). Most of the student were right-leaning. I had expected CU to be a liberal haven, but I was surprised to find that it wasn't, well, at least when it came to the students. It wasn't a conservative school by any means, but the student body was certainly moderate to moderately conservative. There was the student backlash that happened when what's-his-name wrote about 9/11 and the little Eikmans, death threats to one of the openly gay professors, and shouts and graffiti of the word ****** at the basketball, football, and around the African studies building.
The Mountains Sun makes the best beer; if you ever get a chance to return to Boulder check it out.
