to have the peace of mind of knowing you have tickets and where you will be sitting, especially if you are taking the family along.
There are only 2 games where I could not find tickets other than singles....the GT game when Gameday first visited Clemson and a Homecoming game vs Wake Forst back in the early 2000's.
The GT game was just electric with Gameday in town and drew in tons of extra fans.
The Homecoming Wake game was weird, but I believe that since it was homecoming and an absolute PERFECT fall day, that many had the idea of going to the game. That was the hardest ticket to find. maybe 2002?
