Oakland Valley, believe it or not was really bad at one point with the previous people that operated it, and that’s way up state!!!!
I ran bikes at Bridge Hampton, that’s the worse I ever saw… They had sound checks at tech, 50% red line with a sound meter, sound police around the track and you would get black flagged if you were too loud, fined even!!!! We used all kinds of spray cans and elbows on the stingers to get them quiet… On the grid, you heard “sound cops turn 10” so you knew where to roll off the throttle….
It’s one of those things, if you don’t play by the noise rules, you might loose the track…
