As long as it ain't during the Red River War (BOOMER SOONER!!! TUCK FEXAS!!!) weekend I wouldn't mind going to the State Fair - never been to it.
On the other hand, you can get OU-vs-Texas tickets at bargain prices outside Lew Sterrett (the Dallas County jail) on the Saturday morning before the game!
(Some will be forced to sell their tix to make bail.)
