In reply to ebdon:
With regard to the mindless vandalism of some months ago, efforts were made to establish who was responsible. There was a commendable response from the National Park Ranger and the BMC Access Officer provided advice. The Ranger liaised with the police and farmer but legally the offence was committed against the landowner. Attempts were made to identify any cctv footage on the road without success, although it's possible the perpetrators arrived other than by the road.
One positive was a clearing up exercise, undertaken informally by a CMC workparty and other individuals. There were additional offers to help by good folk on here, but it wasn't necessary to take them up in the end, but thanks anyway. Much of the mess has weathered in, but there remain some large blocks as a stark reminder of the sad event.
