After two JT concerts, two Zoo Tours, one Popmart and one elevation, I finally met Edge on the post 9/11 leg of Elevation in Denver at the Pepsi Center. We just hung out at the back of the venue where all the tour buses were parked. There were only about 20 or so folks waiting, as it was cold and snowy/rainy. Up drove an entourage of black limos...they pulled into the back of the Pepsi Center and about 10 minutes later out walks Edge, straight over to us. He shook everyone's hand and talked to everyone. I got a handshake and picture with him. He was very kind and gracious to all. When he had talked to everyone he said "You all better go inside now. You may catch cold!" Awww...
The first time I saw them during the Elevation tour was in Phoenix. We walked to the back of the arena...I think it was the America West arena,which I don't think exists anymore...and Bono had just been out back talking to the fans. One woman showed us her pics with him on her digital camera.
So...you can be sure that I'll be out back of the Pepsi Center in April.
The band has not been Dublin or Ireland the times I've been there. My hubby even knocked on the HQ door, some guy came and answered and said the band was not there.
Good luck...
