The arena has one entrance for GA admissions, that will be on the side by the bridge that connects the arena with Giants Stadium. However, security will keep everyone at bay, behind a fence. However, there are three or four spots along the fence that will allow you through in order to get to the main entrance which leads to the floor.
99% of the people will be gathered by the fence opening right by the GA entrance, but you do not need to do that. Like I said, I was half way across the arena when I got through the fence and I was one of the first people in. There will be a sea of people by the front entrance and thats just an aggrevation you don't need, unless of course you want that aggrevation, which you might.
If I were you, I'd find one of the alternate entrances and you'll be right in front of the line there, then when you get in, run like hell for the main entrance. You'll have to run for about a minute before getting there, but it'll be worth it.
Bono grabbed my hand for about a minute during UTEOTW, thats how good my spot was.
Did you follow anything which i just said? Cuz i just read it and am dumbfounded I think. haha
