I shouldnt really reply to this crap...but...
There are many facts that are left out of those kind of videos/propaganda.
Anyone that thinks we dont have enough open motorized access doesnt spend much time out in the woods. Its flat ridiculous how much easy access there is, stupid ridiculous.
Maybe in that video they should bring up how much total mass is under wilderness or roadless designation as well as the totals that are open to some sort of motorized access.
The problem is that the OHV crowd has had their way for a long time and have created thousands of miles of illegal trails. Now that they're being taken to task for their past track record, they whine, cry, and stomp their feet. Further, the OHV crowd has largely done a completely crap job of policing their own, educating their own, and coming up with funding for same. They whine and cry about buying a OHV sticker and feel that should cover maintenance costs of trails, pay for enforcement, signing, etc. etc.
The other major problem is that the "common man" is screaming constantly that the BLM, FS, NPS, etc. need to have their budgets cut. Those comments have made their way to the D.C. and funding, as well as personel, are being cut significantly. The last 10 years have seen downsizing, loss of adequate funding, and tough decisions being made on what FS/BLM/NPS programs need to be cut. Maintaining roads and trails are some of the first cut, simple as that. Management, maintainence, enforcement, etc. cost money, a lot of money, and the money simply isnt there. Further, the gap in funding is not being made up by OHV groups or any kind of user based fees.
I can tell you for 100% certainity that funding, or lack there-of, is a MAJOR contributer in the decision making process for road closures, seasonal restrictions, etc.
I believe that there are some solutions, but until the managing agencies are being adequately funded, I would expect more and more closures.
While on your crusade to keep roads open for public use, be sure to ask your congressmen/senators to fund the managing agencies responsible for maintaining those roads/trails and those saddled with enforcing illegal OHV use.
