As you know the stadium has changed a lot. Early in- early 70s, there was only a 10 ft high fence with barbed wire. Back then there would be literally 4-5 people deep in the endzones behind the fence. Then there were also a small set of bleachers in the endzones that really weren't assigned to anyone. There were sometimes 4-500 of us.
The 70 Missouri game, they added an 8 foot fence in front of the 10 ft fence and put cops inbetween. Only a handful were able to get in and the crowd got pissed. The band comes marching in and everyone- probably 6-700 people just locked arms and came in right behind them. People were pushing from the back to the point those in the front had to move forward or get trampled- about a dozen band members got trampled- all muddy uniforms- they were pissed- everything was grass and mud then- little concrete. I was 10 and pretty small in second row- so I got pushed forward, kind of concerned about being trampled etc
The next week the extra fence was down. AND there was a huge contingent of cops where the band went in. We would rush in behind when they would bring the ambulance in sometimes. Or organize with another group, they would scale the fences in one area- to get the cops to go there- while we would scale the fences in another.
Then they built the present wall- that really about ended all the sneaking in. They also sealed up and reinforced all the weak spots in the North End. There was a tiny power box about 6 feet up in the south end wall. My buddy would boost me up so I could stand on it, then I would grab the wire and pull myself up. Once on top you had to grab the edge, lower yourself down, jump. Had to do it quickly because back then cops were stationed everywhere and they would chase you. I was caught just twice- they talk to you, let you go- no big deal just try again.
I always went with the same kid and we viewed it as an adventure- it was a blast. Back then they would let everyone in at the half. He was kind of chicken- wouldn't take many chances- about half the time he waited until half. He quit coming once they put the wall up. . I think only one time in 6-7 years of doing it did I ever have to wait till halftime.
