im an older fan too and loved the GA. admit I'm getting too old to do the wait in line thing.. but damn, that was half the fun. it's worth it man. give it a try next time.
cool that they had the seating chart for the miami show in TM
they'll have to come up with some sort of way to break the crowd up (like the heart last time) b/c there is no way security will allow it to be a full on GA with the entire floor.. that was the problem all along with past US tours, U2 has said numerous times they have always preferred the GA approach on the floor but always had problems with security (they did do this on some of the Unf Fire tour but people were getting crushed)
but as Bono said "rock and roll is a release, you're supposed to be able to get off, airborne. It seems kinda stupid when you're standing on top of your seats."
I know this happens all of the time at some shows but U2 seem to be more aware of people's safety and wanting to make sure it's controlled (we all know about the idiot drunk guy that tries to make his way up to the front or the girl that sweet talks her way up)
I was in the heart 6 times on the last tour and never had any problems with the crowd.. everyone was so respectful.. it was great.
but if you want seats, cool.. means one less person in line trying to get in front of me! LOL
