Interesting I thought, and then in a spectacularly disappointing move, Wikipedia swiftly debunked this claim as myth. It seems that the owners, Ken and Beth Wild, have lived and worked here since 1971 (Ken is a sheep farmer), and the road actually forks around the farm to negotiate the hilly terrain.

Boo! Wikipedia, eater of time and destroyer of legend, curse you, and all who write for you! Here’s a BBC article about the couple with a video clip (and despite the sunny image Google provides, this looks like an absolutely miserable place to live).
