The NC seasons are the obvious choices, and I'd put '08 slightly over '96 because of the buzzsaw we became in the second half of the Ark game. Full disclosure, it was also my first season being married, so even the opener against Hawaii(her first game) was a great experience. And the day before the uga dismantling, we got our last ultrasound of my first son. So that season was just incredible all around for a lot of personal reasons.
I'm gonna go a slightly different direction on my third. I think '93 may be next favorite year, even over '06, which was as maddening at times as it was enjoyable. I was 13 in 1993 and attended more games that year than any other. Doering in Lexington is UF lore. The "Timeout" in the slop of Jax was awesome. Winning the SEC in the rain at Legion Field, avenging the year before, was special. And the beatdown of the loudmouth Mountaneers in my first trip to NO and the Sugar, capped such a fun season of games. Even the loss to fsu didn't sting nearly as others had because of how close we were. To me, it was the year that also established us as a program that wasn't going away under Spurrier.
I'll also throw an honorable mention to 1991. For many of the old guard to finally see us win and keep the SEC at BHG in November, it was about as epic a moment as I can recall. Then fsu a week or two later was a great ending.
