As you approach Lettaford on the B3212 (pictured above courtesy of N. Chadwick) from the direction of Postbridge, the road crosses one of the headstreams of the River Bovey on Shapley Common. It has been reported that some people experience an atmosphere of "intense fear" and drops in temperature, and dogs "cringe and shiver" at this location.
