I wear the same shirt until we lose our first game, every year.
This year it's an orange UnderArmour shirt. Unless we're on the road. Then I'm watching the game in my road whites (a white Columbia shirt).
Also new this year: During the baseball SEC tournament, I kicked it with a lot of the baseball player's parents between some of the games at their RV's. Some of them had made orange and blue coozies that say "War Eagle" on one side and "Expect to Win 2010" on the other. I decided that was fitting for football this year as well. I have used the coozie while watching every game, home or away, except the games I've attended (which by the way, far exceeds any season since my last one in school), in which I am using it the entire tailgate leading up to walking to the game. And even then I leave it in my pocket, since I'm most likely drinking a beer on the way over to the game.
