In reply to Klingon:
I suspect the perpetrators of the scratchings under Transformer/Long John were poorly supervised, bored kids. The owner of the 'Joe' scribbling was undoubtedly older and taller, but no less bored....
Where we can we should call out this kind of damage, and take those doing it to task. But Fergal makes a very pertinent point. When I first started climbing at Bowden, it was pristine, very different to it's current state. Lots of of broken rock, irreparable damage to classics, eroded footholds and scarring. All the result of our use/misuse of a very fragile resource.
But no matter how much we post up on here, people still climb on Northumberland's sandstone crags when they are damp, or wet. In my most recent experience it was a group of visitors to the area, who either didn't fully understand the wet /damp sandstone issue, or did and didn't care. (Locals do it as well) Either way this group had traveled some distance and probably felt compelled to climb....... You can lead a horse to water, but...
Bouldering, with repeated cleaning, and groups banging away at problems is particularly destructive. It's not the end of the world if a climb or problem is too hard for you. You can walk away, and do something that doesn't involve hammering the rock, if you have the humility to do so.
But all of this has been said before, and sadly I suspect I'll be saying it again next year. Meanwhile the crag is rapidly heading towards the North Sea. It is in our power to slow that process down by improving our practice.
