Barry Hodgson stabs his shepherd's crook towards a 1,000ft (305m) fell dotted with great sandstone boulders. "I've got 110 acres of land and that is my only vulnerable point," says the 68-year-old, as his border collie, Joe, squats by his muddy boots. "I know that's where they are coming in from but I just can't stop it happening."
