Well, you'll find out on your own, but sadly, Big12 fans are not like TCU fans generally. ISU fans are VERY nice - much more so than us - you will like them. KSU's are friendly and respectful. KU (in basketball) are arrogant and disdainful but in football are "not there" or "absent." Otherwise, "nice" wouldn't be the word I would use to describe the others. The Eers are friendly but have a weird obsession with couch-burning. The Red Raiders like to throw things (usually tortillas; sometimes batteries) at you and curse you. Lately, the Bears like to rape you and then cover it up. OU and OSU are okay, but they're from OK and hate everything from Texas, so it's not a good start. Longhorns will barely notice that you exist and will consider you beneath them even after you stomp them.
