I know by previous posts that many of you guys have spent many happy hours tramping around Penwith in West Cornwall. Although I live in the east of the county I've never visited the west yet on a stones mission but that will be changing this year. I wanted to ask a question about the holed stone at Men-An-Tol. Does the outer ring of the holed stone continue as a ring like a doughnut, or does the outer section where earth-fast have a spur on it that sockets into the ground to hold it secure? Cheers, Roy
