I thought from your first post you’d bumped into this guy in the pub, didn’t realise you had met him on the trail itself. We don’t ride that much maybe twice a year tops, I can’t see how he can own it and I’ve never met any dog walkers on it. He probably saw some lights coming down the hillside in winter and your the first cyclist he’s managed to bump into on the trail that he can vent his anger on!
