In reply to Alan James - Rockfax:
I've just notified Rob Dyer, Andy Reeve and Jon Fullwood so that they're aware. Andy has experience from removing the spray paint/graffiti up at the Cowperstone a few years ago, so has a good idea as to how this is best done.
Andy, if you happen to receive this before you see my email let me know if you want a hand in getting it done. I may have to bring a toddler along to help, but I'm happy to give some time wards lending a hand.
