There was a sack city sign years ago in the DII era and I loved it. At tailgating a few years ago a guy told me he had done the original one but it was long gone.
It inspired me to make my own so I enlisted my wife to help me. She thought I was crazy but after a short trip to the craft/fabric store we made it. I had an old picture of the original and tried to match the lettering as best as I could.
We hang it behind the visitors bench but sit on the other side so we enlist the students sitting by it to run the thing during games. Last year we had to move it down closer to the band because there were a group of students that hung over the railing and pounded on it while harrassing the visitors. They must have pregamed pretty hard because they were lit up for every game. I fully endorse the work that they were doing but it was a little hard on the sign and the paper numbers. I figure it just added some character to it.
We live in the TC and won't be at any games this spring but will be back in full force next fall.
