The southern and midwestern schools have a tradition of welcoming opposing fans and being gracious hosts.....generally.
In the west, it seems that the fans are all about trash talk. At the Arizona game a few years ago, a drunk student yell, "___ you Mormons" right in my face while I was holding a toddler. At an ASU game a couple of years ago, a drunk student also yelled something pretty vile to me while I was walking with my kids and I happened to be the only one in my family wearing the opposition's colors (all my kids were in ASU gear).
