This problem is epidemic across the country. The fact is that enforcement is severely lacking in terms of catching these people. But, who wants a game warden around every corner? I would like to think there doesn't have to be. . .
The real solution is teaching young kids the value of hardwork, of roadless country, and the right and wrong way of doing things. This takes lots of dedication and time. It's called parenting and having a shred of self respect. The people who do this never learned the value of these things. They are lazy and don't care about having special places in this world where there are no roads just for the sake of having them. They don't care that the amount of roadless wilderness in this country is down to about 5%, with over half of that occurring in Alaska.
They're rewarded by driving off road because they don't have to work as hard and they still find sheds, and they rarely if ever get caught.
