Update, I did end up with 3 GA for a different city than I originally wanted after checking again after about an hour. No Red Zone available at any venue. For the first hour of the presale, I would either get "Unable to Process Your Request" or "no tickets available" messages, or in some cases, offers of 300 and 500 level crap seats.
My frustration is that the fan presale that just does not work. It hasn't worked well in past tours, but seems to be getting worse. Ticketmaster sucks, which is a given that we all are apparently doomed to just accept in life. But, U2.com shouldn't take our money for a "benefit" that apparently doesn't exist. Just look how many good seats are already on the scalper websites. The system is a con.
I love their music and I love their shows. Have been to every tour, and bought every album since the first day I heard their music in 1982 or 1983. I have been an on-and-off member of their fan club since the old Propaganda magazine days. I understand that they are popular and that there is a high demand for tickets. But, it bothers me that they don't take this into account and that they treat their loyal fans as commodities. If presale doesn't work for a band like U2, then the ethical thing would be for them to not have one!
