Had a call from Stephen Moores - the bailiff for the Wye - today, they are having problems with poachers in the vicinity of Raventor. He didn't seem to think it was climbers, but will be policing the area heavily for the next few weeks and mentioned there have been climbers camping in vans at the tor. If that's what you're up to, and you don't want to be rudely awoken in the middle of the night, he suggested putting a note on your dashboard, though I daresay a rope and gear might suffice. Likewise, if anyone has been there late and seen anything suspicious, information would be appreciated and would help with the improving relationships between climbers and fisherman in the dale. PM me and I can pass on his phone number, though he regularly passes the tor in a pickup with a wooden box on the back.
