The environmental extremists are slowly taking away the motorized rights of all outdoor enthusiasts. What possible environmental harm comes from riding on sand dunes? The next strong wind rearranges all the sand anyways! Snowmobilers are having the same problems. When used on adequate snow cover, snowmobiles don't do any environmental harm. The snow melts in the spring and the trail just looks like any other overgrown path in the woods. All motorized users need to unite and answer back to the big money eco-terrorists, most of whom never even get out far enough into their beloved wild areas to even appreciate them anyways!
