Similar experience. Went to the 94 game. A bunch of 20-ish guys in front of us drinking all game. One dressed in a gorilla suit with jungle print underwear and an Iowa flag around his neck. That dude started hitting on my mom (with my dad next to my mom) putting his hand on her leg, etc. By the end of the game he rushed out on the field security guy in chase. Great picture of him eluding a 275 security guard.
Best part is I saw same dude on espn during basket season rush on to the court and do a layup during the Iowa Northwestern game
So what you are saying is that our fans are awesome.
