Well, I don't know if that is still the case. I had a bit of a chat with the bloke yesterday and his take was that the landowner had banned climbing completely a few years ago after someone fell, broke their leg and tried to sue the landowner. So the impression I got was that the farmer wouldn't be giving permission to anyone.
This ties in with what I heard from friends last year that there was no chance of getting permission so you'd got a choice of going and trying to stay below the radar and take the chance of being asked to leave, or not going at all. Obviously if you've managed to get permission for a visit more recently then that totally invalidates what I'm saying and would be good to hear.
