I've got hundreds of stories about OU fans, but I'll relate just one. Went to Angel Fire skiing, always lot of gooners and tejans there, I"m standing in line to get lift ticket and a guy dressed in OU gear from head to toe is standing in front of me. I happened to have on a black fleece pullover with a small powercat on the breast and he turns around and looks at me, then he sees the logo and looks back up at me and says, BOOMER SOONER, loudly, and then tuns around without saying another word. My daughter, a KSU student at the time, and I started laughing and have laughed about this incident many times.
Also, I'm guessing only 10% of their fans have been within 50 miles of the campus.
