The more I think about it, the more I realize that the U2 show last weekend was the best concert I have been to. Great seats, great sound, amazing stage setup that added to the performance of the band, and a band that really loves what they do all came together for a perfect night. Wikipedia has a good article about the stage setup and it answers some of the questions I had about the stage. There are three stage sets being leapfrogged on the tour, they use 120 tractor trailer rigs to move it, and the band is offsetting the carbon dioxide produced in moving around all that huge equipment.

Here are some pictures I took of the stage. One was during the break between the Black Eyed Peas and the U2 shows. The second is right after the concert at 23:50 and the final is about 0:26 as they are breaking it down.
