Just when leaving the site one of the men who lived in the houses, opposite, asked what was happening. Looking at the stone was my answer. In return he explained that his granny had attended the nearby primary school. She had said that stone had a sad face because a rival had stolen his mate and pipe, the mate being part of the circle presumably, and then went on to steal gold at Skelmuir Hill.
(I know about the Skelmuir story, the pipe/mate story well........Still, if you don’t ask!)
These people are just desperate to tell you their stories. I think it's great.
