Since Lance asked, I'll try to provide some sort of synopsis on my position regarding vehicle-based recreation versus wilderness. But it's impossible to do in fewer than 50,000 words, because the subjects really can't be explicated with the sound bites that some here have tried to use.
First, it should be obvious from the fact that I co-founded a magazine devoted to vehicle-based expedition travel that I love 4WD vehicles and motorcycles. I own three of the former and one and a half of the latter. That in no way prevents me from also cherishing wilderness, any more than liking Bass Ale prevents me from also liking Johannesburg Riesling. I'm weary of the assumption that one has to choose a loyalty to one or the other.
4WD owners scream about road closures, and conveniently like to attribute them all to those evil “enviro/socialists,” as someone right here just described people such as myself. Wrong. Most road closures on public lands are the result of, a) budget cuts, and, b) illegal roads. The U.S. Forest Service, to name just one agency, is decommissioning thousands of miles of inventoried roads because it simply doesn't have the money to maintain and police them. If you want to know which administrations are responsible for cutting the most out of the USFS budget, go look it up. If I listed them here it would tip this discussion over into politics.
Illegal roads. Are they created by enviro/socialists? No; they're the result of irresponsible 4WD and ATV and motorcycle owners. Think it's a tiny percentage? Wrong. Here's the result of one study, in Montana:
In 2006, Montana Fish, Wildlife and Parks received survey responses from 446 owners of registered off-road vehicles. Among the full sample of respondents, 23% “always or sometimes” ride cross-country even though off-route riding is against the rules in Montana and has been since 2001. Over 28% “sometimes or never” avoid riparian areas and wetlands, in violation of rules for federal and state public lands in Montana.
Sixty-four percent of those surveyed have used an off-road vehicle while hunting. The majority of this hunting subset admits to riding cross-country — over 58% have traveled off of legal routes to retrieve downed game.
And those are just the ones who admit it. I could put up the other studies I have, but trust me, they're the same.
These results have been duplicated in other states. Irresponsible use of 4WD vehicles is not marginal, it's epidemic, and growing with the number of people buying, especially, ATVs, who have absolutely no sense of wildland stewardship or ethics. Many of them truly believe that driving those things cross-country does no harm; many more of them just don't care. I deal with this issue every day outside my front door. Every day. All it takes is one moron to cut a trail where there wasn't one. The next guy comes along and sees the tracks, “Hey – there's a trail!” And before you know it there is one. And then after a year or two or ten, when a land agency closes it, guess what? Yep, it's those evil enviro/socialists at it again. My wife and I have worked on the ground closing illegal roads, and will do so again. They're bad for the landscape, and bad for the reputation of 4WD owners.
So. Are you concerned about losing access to 4WD trails? Then do two things. Vote for an increase in the USFS (and other land agency) budgets, and fight irresponsible vehicle use. Quit blaming it on “enviro/socialists.”
Wilderness. I'm not sure how to approach this, because, truly, I can't comprehend the mind of someone who can't appreciate the concept of places where vehicles simply don't belong. If someone were to say to my face, “Wilderness designation is a failure,” I'd probably just walk away, because I will never be able to hold a civil conversation with that person, any more than I could with someone who tells me, “All four-wheel-drive vehicles should be banned.” Each statement is equally blind and self-centered—and wrong.
Ninety five percent of all the land in the U.S. is not wilderness. To me (and, I need to add here, a majority of the American voting public), that's a sad legacy of what we were granted by God and nature when we colonized this place. So, yes, I believe that our meager remaining lands that retain viable wilderness potential should be given the opportunity to be protected as such, including lands that might have a road or two in them which could be closed, if the benefit to the habitat and wildlife is strong and public support is there. (On the other hand, I'm perfectly willing to have land managers carefully consider new roads in areas devoted to vehicular recreation, again if the situation and public support warrants.)
Wilderness doesn't “lock up” the land. However, wilderness designation does put the welfare of the habitat and wildlife above our own recreational convenience. That's in the original blueprint for the Wilderness Act, and I believe that mandate speaks highly of us as a society. There are plenty of wilderness areas I'll never have the opportunity to visit, but I'm happy knowing they're there. It cuts the anger I feel when I walk out in the morning and find yet another set of tire marks scarring the desert. (Then again, you want to see me really angry, be with me when I find the border fence to a wilderness area cut and vehicle tracks headed right on in.)
Are there problems with wilderness designation, and with some wilderness proposals? Spare me. Of course there are. But those problems are specific, not conceptual, just as are the problems with selfish vehicle owners. Don't agree with me that we could use more wilderness? Okay. But claiming that wilderness designation is a failure marks you as just as much a fanatic – and just as problematic for those of us trying to balance use with conservation – as those who claim that vehicular access is a failure. Those people are all part of the problem, not part of the solution.
