Well Calvin, one thing is for sure...you clearly love the public lands as much as I do and many others! We have similar problems here in Colorado as referenced by Redrockman and Jamesr. Maybe it is because of proximity of larger populations - there are just bound to be more problems. Roads that end up being closed are typically not "roads" at all, but rather just routes and shortcuts that were made by people just driving through a meadow or up a hillside. Over time, you end up with what looks something like a road but should have never really been there. They can cause much erosion, which then ruins the water which then affects the hatches which then affects the wildlife and on down the line. Not to mention, they often look pretty bad. Judging by the picture in the newspaper above, this might be one of these informal "roads", but I don't know the particulars of that specific situation.
I'll bet some of the guys on this forum wish they had public lands in the east the way we do out here. Perhaps they will take some solace in the fact that our public lands are every bit as much theirs as ours! As far as the rangers closing some routes as they do, I have little problem with it. I don't know of a land owner in this country who would just let people drive wherever they want to. I expect the same level of care for our public lands. It is a privilege to enjoy some of these old roads exploring around by jeep, not a right. Just my opinion.
