Always Alabama. When the last black hole radiates its final quanta of energy into a dead and exhausted universe, leaving behind a degenerate motionless soup of photons and neutrinos resting in a finality with neither beginning nor end - there, in that timeless nothing, you will find me or my spirit - still hating Alabama. Because I hate them. I hate them so very very much.
Uh, after that, Florida, but the further we go from the 1990s, the less that is true. After those two, lesser but still very real, Vanderbilt (in-state and conference pride, as Vandy was once a big time rival), and Kentucky (a lot of cross-border family between UT and UK).
