I toyed with the idea of bringing my camera, but the tickets clearly had "no cameras or recorders" printed on them, and I didn't want to chance anything. I also had heard that the band is fine with people bringing cameras as long as they didn't flash. But I weighed option A (shiny new expensive digital camera confiscated) against option B (I get some mediocre pictures), and decided that I'd be better off.
You, on the other hand, might get some good pictures from the second row, so your equation is weighted differently.
