They didn't check anything. They just swiped the card without looking at it. Didn't have us empty our pockets. Security said as far as cameras, "If it fits in your pocket, we don't care.". Loved it! Only GA for me from now on.
Just got an email from TD Garden . They say that security will issue numbered wristbands starting at 8am each day in the foyer of stair 4,just past the box office on the west side of north station. We will be able to line up there again at 5pm.Gates will open at 6pm.
Found this TD Garden venue policy sheet, not specifically for U2 . http://www.tdgarden.com/docs/GA_info.pdf
I'm concerned about the "no cameras of any kind". Point and shoots without interchangeable lenses are always kosher for past tours.
