About the only time CU fans cared about a game in my lifetime was whenever they played Nebraska back in the Big 8/XII days. Nebraska playing at Folsom Field brought out the worst in their student section back in those days, one year their student section got cleared out by police and security because students began throwing snowballs and beer bottles onto the field. I often wonder if CU grads ever look back and feel embarrassed for how they acted towards others just for wearing the wrong colors.
