FWIW they use metal detectors at LVMS on Midnight Mayhem and other events as well. Just sayin

I have attended a lot of grudgenights at a lot of different tracks. I would say most are at best somewhat organized chaos. Generally the starting line area is packed with people and there is always at the very least one fight. I have also been at San Antonio Raceway when the police had to be called and the night was shut down due to some violence in the pit area. Must say HMP is not far from Yellowbelly in terms of atmosphere and they wreck as many cars as any track I have seen.
