I ride a Praire 700 with 589s, my 20yo rides a 400 sportsman and my10yo rides an eton 90. (avatar) We found the best riding at the Hatfeild McCoy. Having done those trails for 5 years straight. It tends to be the same old terrain. My try Maine this year.
Where I live, Southern NewJersey there are places but its more like a network of friends who know where its safe to ride. The most polluting of the enviroment from what I witness is the Contractor who decides to dump his roof shingles or trash anywhere he pleases. And not subjected to any penelties whatsoever.
But take a atv out for a ride......look out, arrest him, fine him, impound his vehical, an in some cases suspend his drivers license.
Not many if at all atv-ers will go riding with the agenda of dumping there garbage where they ride. Ive seen abandoned cars sumbmerged in water on National Parks. And trash everywhere.Refrigerators hottubs sinks you name it..... Atv-ers I doubt it.
I have about 150 acres to ride on in my back yard with no hassles. Some people just hate anything motorized in the wilderness.
Btw. kudos to West Virginia for having put together one of the best riding experiences in the country. Other states are noticing how successful it has become and the commerce it brings.
