Rob, I'm not trying to be difficult... But in the 100 years (or whatever it actually is) of use prior to the court issuing a ruling supporting a prescriptive easement you still have the easement, the court only affirms it. But if prior to that ruling the trail owner, de facto or otherwise, stops using it, or states it isn't interested in an easement anymore then the public is hosed, the private land owner wins, and a potentially completely established legal prescriptive easement, perfected over decades and decades of use is lost.
The judge ruled is simply that the FS is not required to pursue prescriptive easements, I think everyone recognizes that is the case. My counter to that is that doing what is right shouldn't have to codified. The fact that the public agency most strongly aligned to protect public prescriptive easements to National Forest lands can simply choose not to, when an anti-public land administration comes into office, and after 5 years, the last 100 of access and work to maintain that access are erased, should chill the hearts of public access advocates.
This isn't a "yes" moment, in anyway that I can conceive it.
