Oklahoma fans are really good hosts and very classy as a whole. Have heard many a story like this over the years and have never witnessed anything but stories like this on my many trips to Norman.
Classy. In general in all the games I have been at in Norman I think our fanbase shows opposing fans a lot of class. The great fans way outnumber the classless fans.
I can personally say I've never witnessed a single fight between fanbases in Norman. I've seen drunk college kids fight, but they were all ou students. I've seen fights in Dallas on ou-Texas weekend, but I've never seen anyone in Norman get in a fight with a guest. That's my anecdotal experience. I'm not sure I've even heard someone in Norman yell at a guest. Seriously.
