I belong to an off road motorcycle club over in west Marin County, The Marin County Motorcycle Association. The club leases 1200 acres of the owners property. There is an extensive network of trails. Nice big club house, the whole bit. When a trail has been used up it is taken out and rehabed and a trail put in it's place. One of the club rules is that you STAY ON THE TRAIL. No making your own trails. If people are found to behaving badly we have our own BAN HAMMER. At $500.00 a year dues a six month suspension really hurts. This years makes it thirty years as a member for me. My son and younger daughter are also members.
