Well, when we were up there last year, it was a friday there was no one standing at the gate checking for anything. But on Saturday they were out in full force!!!
I was up there with a new set of toomeys and no "sparkys" or hush kit.
They wouldnt let me in But I will say they were very polite about it,I knew what I was getting into but I figured I would give it a shot
If I were you, I would get some spark arresters and make sure you are not too loud!!!
By the way that trip we took was in April of last year. From what I hear they are not to strick at that time of the year.Ive been to Silver Lakes a total of 15 times and never have been checked for decible level
Or,If you have a pickup truck, just put the quad in the back, drive the pickup into the dunes, park on the beach, and ride
