Even the Cotton Bowl itself is demarcated clearly into Texas and Oklahoma sections, and one could draw a line into the stands at the 50 yard line clearly separating the two fan sections.
While this matchup perennially determines the winner of the Big 12 Conference, during my visit this game even took on an even greater magnitude as Oklahoma was ranked #1 in the country at the time, with Texas only a few spots down the ladder at #5. Furthermore, it featured a head to head battle between two Heisman hopeful quarterbacks in Colt McCoy and Sam Bradford. When they say everything is bigger in Texas, they don't make football games any bigger than this as 92,000 other fans can attest.
In a classic gunslinging Texas shootout, the Longhorns prevailed on this day running away with a 45-35 upset victory.
