Heh heh!
I reckon what you were saying about the approach from the farm being a better idea than across from the How Tallon might be part of the reason you homed in on it. The carefully chosen route did give a better idea of the lie of the land. Maybe it's easier to find the stone if you've followed the markers on the north slope cairnfield. Hmm. I'm gonna ponder that as I go kip. I wonder if there's another one with as much 'oompf' on the east shoulder of the Gill...
Megalithic hat mould, heh!
