I have seen U2 here every tour since UFF ('85 front row center - 1st ever scalper tix)...through Vertigo tho' I missed Zoo and Pop due to starving artist issues. Every show (crowd wise) was amazing except for the Vertigo tour (from just outside the elipse) where the crowd seemed very "rich." It just felt like the entirety of the crowd didn't really catch the vibe that is necessary for a successful U2 show. That changed when Bono pulled Sunjay Devarajan out of the crowd to do Angel of Harlem and the energy level was through the roof through the end of the show.
The whole point is, you have to count on the band to gauge things and make the adjustments that ups the energy and makes the show exciting...I have never been completely disappointed in a U2 show and don't know if I ever will be...even in Dallas. Just my 2 cents.
Hope to see you here...I will be...Red Zone...I can't leave getting close to the stage to chance as my 11 year old son (his 2nd show) and 5 foot tall wife (her 3rd) will be there with me so this is the best way to make everyone happy. I can't wait!!!!
