Never had an issue with Tennessee fans, although the walk back to the car in 1998 was kinda scary. I chalk that up to finally beating us after five years, and winning in OT.
Bama fans in the 90s were pretty respectful of UF and vice versa. The Bama fans I encountered several weeks ago were also very respectful. No issues with them at all.
LSU fans are rowdy as hell, but if you play it right they'll treat you to some awesome tailgate grub. You just have to be a good sport. LSU fans on the road are worse than they are in Baton Rouge. Had a kid yelling Tiger Bait during the national anthem in 2008, and he wound up getting ejected before halftime. A group a LSU fans about started a riot when one guy in the group attempted to take a piss on the big gator outside the north end zone. Very rowdy fan base.
UGA fans are among the most delusional on the planet. I don't hate them as much as I pity them.
