Unfortunately the next set of bolts have not yet arrived from Germany so the work planned for this coming weekend has been postponed. The new date is now Sunday 18th July. I will update this thread with confirmation nearer the time...Thanks
I think the biggest problem is broken glass/bottles/litter to be honest - there seems to be a hell of a lot more of it around the bench/base of the crag.
A lot of the bottles etc seemed to have been thrown off the top of the crag rather than littered from in the quarry.
