They've only been to CoMO once for basketball last yr's Border War and once for football '10 OU.
They were in KC for the '07 Border War football game and at TX for the '08 football game. They might've been at OU for the '07 football game but I'm not for sure. Maybe the Big XII CCG in '07 too. I can't remember those two one way or the other.
Not sure where else but I could be forgetting something.
