In reply to Neil Williams:
Can’t be sure, might be a local council in that case. Presumably whoever owns/ operates the woodland there. Nonetheless it is a localised response and demonstrates people aren’t happy. It’s probably not about climbers specifically. I have also recently seen cars parked on the (no parking) bit opposite the turning circle being leafletted with ‘well done for parking like a tw*t’ posters under their wipers: presumably not the council. Either way if you’re headed that way then you might want a backup plan.
