Call me capricious, I am not an unbeliever at all. I would employ a diviner like a shot if I could find a reputable local. Years ago when the Rollright stones (somewhere by Chipping Norton) were guarded by an eccentric lady called Pauline, she showed me how to divine for ley lines. She gave me some metal rods in plastic holders and had me pacing up and down and around the Kings Stone and The Crone. Well this is over 25 years ago, but I enjoyed the experience and thought the rods moved for me at the time.
