I had NO problem with the restrictions.
I was with three other buddies last night in 159, we all got up to get beers together, got 4, sat back down.
We didn't wait in line long. But then again we knew of the restrictions from the three articles in the paper.
By the 8th inning, we were in the bullpen bar where there are NO restrictions.
By the way, if you have season tickets in the upper deck ( like I do) they allow you onto the main level.
