Not sure which point of view you mean now Dave! I was definitely in the resurfacing camp, although really all I'd like is the spectacular number of potholes filled in with ballast, not a big ask. I never expected it to be the council's problem either as it's clearly unadopted as a road. So it's up to the owners of the lakes buildings and/or local volunteers in the valley project (or indeed us) to sort it.
If speeding ever became a problem, then take action to solve it, it shouldn't mean leaving an important access route to such an asset in a practically unusable condition. You could even say that people speed down there now because the track's in such a bad state they think or know they'll be the only vehicle on it!
Chadkirk is a good comparison. In fact, the lakes might be improved by similarly making a new car park closer to the main access road, solving all these problems AND forcing people to walk a bit.
