I've been fortunate to be in attendance to some great games and I'm not a season ticket holder. A couple of games that I would put in the "loudest" category and were kind of unique involved 2 SEC tournament games.
The first one was at the very first SEC tournament that I attended and was in Rupp vs UT in 93. UT had beaten UK by 1 in Knoxville about 2 weeks earlier and the Cats came out firing on all cylinders in this one. The crowd just got louder and louder as the Cats continued building their lead eventually to a 61 point victory(101-40).
The second was in 95 at the SEC tournament against Arkansas. This one was special because it was a loud before, during, and after the game. Maybe the best overall basketball atmosphere I've experienced.
It started before the game with a Pep rally out on the street between the Georgia Dome and the Georgia World Congress Center. The Arkansas band, cheerleaders and fans were on one side of the street and the UK band, cheerleaders and fans were on the other. I'm talking thousands of fans for each school.
Then during the game it was back and forth between the fans as well as the players in an unbelievable game in which Arkansas led at half 50-44 after being ahead by 19. The Cats fought back in the second half to force OT. In OT Arkansas scored the first seven points and was ahead by 9 with a little over a minute to play, but again the Cats fought back and won!
The really amazing thing after all of that was how loud the UK fans were coming outside of the Georgia Dome. It was so loud and wild my two 12yr old stepsons were holding mine and my wife"s hands. Very unusual for them, but that's the effect it had on them.
Those standout to me even though I've been to several Final Fours and the famous BasketBowl in Detroit with like 85,000 fans.
