I've just added some pictures and fieldnotes for my visit to Thimbleby Moor this afternoon. As a relative megalithic newbie it was great to be the first to provide pictures and notes for a site. The land is private, but I know the gamekeeper and would be willing to accompany anyone who fancies a visit.
There's a completely round wood nearby that appears from the road to have a low bank and shallow ditch just inside it. I plan to go back and give it a closer look sometime soon.
