That's pretty hilarious. Two of my friends made it a mission to get into gator home games free when we were in high school. They succeeded many times, and only failed once that I can think of.
1 way they got in was buying shirts that said "staff" and buying 20lb bags of ice and just walked straight past security with the bags over their shoulders. I think they used that one a couple of times.
One of these times they just tried to sneak by, got stopped by a cop, and they said, "we are supposed to meet Mrs Aubrey here to work a booth" because Mrs Aubrey seems to know everybody. Sure enough, the cop knew her and started talking about the stories he had about her then let them through.
My favorite story is the failed attempt they told me about. They walked into BHG the day before when it was open for people running stadiums, with the plan to find a spot to hide all night and come out the next day for the big FSU game. Well the plan worked and they found a nice hiding spot, but a cold front came through that night and they had no warm clothing. Air dropped to the 40s and froze them out of there.
I believe they also made it their mission to get down on the field one time and did it by just bringing some clipboards with them and walking out there. Could be confusing their story with another, though.
