The very first I’ve heard of his issues, or, that a section of the road was private.
I’ve/we've always ridden slowly past his house and stopped or waved hello to anyone there. I’ve helped a few people I’ve come across, casevac’ed/pillioned a broken wrist out and heard of some nightmares but never thought someone was grinding his gears about it.
He’s obviously one of those guys who would never ask a cent or say No to rescues or requests, even if it costs him precious time, money or sanity. It’s worn him and his family down and now the straw has broken the camel’s back. We and he can bitch about bad behaviour of bikers and 4x4'ers, but, he's been passive about this until now.
Of course, if the route is over private land and he wants to close it, that's his prerogative. However, if he simply put up a sign at both ends both educating people on how to behave and that there will be a cost attached to both using the trail and a reasonably stiff fee if there needs to be a recovery. Use a deposit box at the farm or Snapscan and I am pretty sure he’d be a happier man.
Unfortunately, guys like this, once they've made up their minds...
