I don't know how others view this, but I prefer not to play nebraska - at least in football. On some level the nostalgic hate is kind of fun (which is the point of this thread), but on the other, the husker fans that come to Boulder are such raging assholes, that I prefer not to deal with them. No other fan base shows up so rude, so in your face (okay, maybe K-State) and so provocative (okay, maybe CSU too). But it's not fun, when I'm trying to be welcoming of other fans, for them to be so overtly confrontational.
For the record, I don't think that's how nebraska fans behave around other fanbases, but in my experience, that's how they are in Boulder/Folsom, and I don't really enjoy dealing with it.
