There actually were free tee shirts, for women’s basketball, but you had to be there for the start of the women’s game for one of the 500 they were giving away.
The guy in the box office said they still had some when I bought my ticket, but they were gone by the time I got to the door.
I did manage to get one for my granddaughter though. Two students wound up sitting right in front of us. One of them had 2 tee shirts. My buddy asked him, no begged him, for the extra… ..and he was nice enough to give it up.
