Didn't mean to open a can of worms, I'll search around and get your thoughts.
Out here we are dealing with two ordinances, one in Riverside County and the other in San Bernardino County, in addition to the two ords, we have a State Senate bill that is still on the table, these ords and bill, if passed will pretty much kill riding in Ca., they propose to restrict riding to 3 day a week ( Tues, Thurs. and Sat ) between the hours of 8-7 on your own property regardless of size and location; They will also make it illegal to ride anywhere in the unincorporated areas of the county that is not an approved OHV park unless you carry permission from the owner.
This whole thing is base primarily on excessive Sound level; Dust and irresponsible riding in the urban areas are an issue also, but sound is number one.
If these pass, there will be no trail riding as we have now, nor will the district be able to hold events, due to the fact that our venue is checker boarded with private investment properties and many of these investors don't live in Ca. or the USA for that matter, so we lose a venue that we've had since 1932.
But here's the scary part, these ords are being watch by counties outside the state of California, these are models that other states want and will impose; So, for many other us, there is no greater issue than Sound levels right now.
