FWIW, a friend of mine in CO tells me that Colorado State has a large and enthusiastic fan base in the state, mainly because it is the main university for in-state students. He told me that CU has a disproportionate number of out-of-state students (including a lot of CA students who go to CU for the chowder and blow), making their fan support in-state relatively lame. Just thought that was some interesting insight.
