I was at Lebanon Valley center front for that tour. Amazing concert. I managed to get out before the worst of the rioting. The car flipping and burning had already started in the parking lot though.
I saw them at the International Amphitheater in Chicago with Sabbath. Great concert, surprisingly, nothing too crazy happened except someone on the main floor had a blowtorch that when he fired it up went about 10 feet high, he lit it off every so often until security nabbed him. Good times.
