Chicago will be my third U2 concert and my first GA. I'm 5'4" and the friend I am going with is shorter than me. After reading some posts, I'm wondering if we will see anything!?? Also, we will not be in a position to stand in line from 5 a.m. on, and instead, probably won't be able to join the GA line till about 5 p.m. So, what would you guess our experience would be like, and do you have any tips? Hopefully tomorrow morning, I will snag a seat for the second show.
