A surprise - Stone 66 is visible. I'm not sure if it is where a bunny has scratched or if I just have never noticed it before, but the beautiful smooth domed bluestone top is partially visible.

(Of course it means I will have to update the http://www.sarsen.org/2012/11/91-total-number-of-visible-stones-at.html page as well now.)
