I've been to Arrowhead a few times, and I'll say it was fricking loud, and that was against Detroit and the Bills and not KC's divisional opponents. That's all the credit I'll give to KC fans though. A lot louder than the good ole 1990's days with 80K in Rich Stadium when I had a young set of lungs. However, Len Dawson said on last year's pregame, if there is someplace to challenge the record, Orchard Park would be in the running. Do it people!! If OP broke the record I could bring that up at work........for the next few months, every day. I love Rex's pressers and don't feel embarrassed to drive with the Bill's laser tag plate and damn, that feels good, keep it up Bills!!
