I had an appointment at the UofI hospital a few years back, and someone ripped off my Cyclone State sticker off my car in the hospital parking garage.
Another time, when I was like 11 or 12, I got free tickets to a Iowa game vs Indiana, and I made the mistake of wearing a non-Iowa State red shirt with gold lettering. My friend (same age as me) and I were just walking around exploring the place before the game, since it was our first time at a game at Kinnick, and some ****bag chucked a glass beer bottle at us walking, but luckily missed by like 3 feet. Chucking a glass bottle. At a 12 year old.
