Staying at the nearby hotel I came out last night to try and find this but quickly gave up rather than poke around in the gloomy night. I’d brought a torch for exactly this kind of purpose but accidentally left it in the car… and the car key in the hotel room!
This morning, though, was much easier. The hint object – which I hadn’t even been able to see last night! – was a great clue and I was about to find a root… I mean route… to it through the undergrowth. TFTC!
