you dont really have to touch a post if you use a ladder, but thats kinda stupid, really fences should be set back from the actual property line IMO, at least a couple feet, that would resolve this issue quite easily. My guess is the biggest problem is that some of these landowners bought their land at inflated values because they thought it would always give them exclusive access to the public property thats adjacent to their land, or they are guiding or allowing guides to access that land for $$$, its aways about $$$ and greed when it comes down to it, otherwise who really cares?If the problem of crossing at a corner is ypu physically “touch” private property by going over …. Wouldn’t permanent fences and posts that are on the corner be touching or set on public land as well? It can’t be one way or another….. where does the private ot public start? If a rancher puts a corner post in technically it’s being placed on public land by the same logic being used…. those permanent structures need to be set back off public property?
