A: The evacuation in 2012 did change the way large-scale events address safety and evacuation. We had planned on paper, but in 2012 we were faced with a decision about whether to evacuate. We started the evacuation an hour before we needed to, almost like a dress rehearsal, and then the storm did hit. It turned out to be the right call (to go early) because it became very unsafe with high winds. We learned a lot and our industry learned a lot from that event. It’s all based on wind speed and lightning. The show can take rain all day long – the Foo Fighters played through rain (in 2011), but there was no high wind or lightning. If the wind had hit a certain threshold and lightning hit within a certain perimeter, we would have canceled that year too.
