Yeah, I grew up in rural WV, mostly. There's lots of logging roads on private property, and my understanding was and is that unless someone else owns a right of way, the owner of the property can deny access to other vehicles, and that people too young to have a driver's license (or otherwise not in possession of one) can drive (usually farm tractors and little ATVs) on these roads with the owner's permission, whereas it's illegal (although some people in WV would say "technically illegal" and try to do so anyways) for those people to be driving anything on public roads.
Thanks for telling me about the Golden Road. That was new to me, and I'm glad to hear of it. I take it that no one gets tickets for impromptu races on that road, even as there's no trouble with the planned events. My dad once told me that California has a law against maintaining a feature on your property that makes it attractive for people to behave in a hazardous fashion, but I don't know that Maine has any similar sort of law.
I have to agree with you that hiring work done by auto mechanics is often worthwhile, but I think you'd agree, that understanding what's going on well enough to do some basic rudimentary quality control can often be beneficial. Having done a fair amount of mechanical work in the past, I do feel obliged to mention that if you're regularly smacking your knuckles, you want different wrenches, although, certainly the different wrenches being ones in someone else's hand does the job just fine.
