Even in the "dunes", absolutely run the spark arrestor! The edges of the dunes (where you will be camping) have trees and brush and God knows we don't need any more brush fires here in Calif!

 

Recon probably knows what the ratings are in Cali, but I think most places that have limits are at 96-98db.

I've seen people in here say they've gotten fines, some were told to park it (makes for a long walk back) and a few that have been impounded.

I think mostly it will depend on how you handle yourself, but even then, you still may just find the one officer that's gonna be a pain.

 

96 in Calif.

While one will probably not get cited at Glamis, Pismo is another story.
