Hi Rocknicker!
Good to hear/see you. Hmmm..... rock art adventures, he?
Skipp the 'bloke'; lets go for the farmer! Was it the owner/tenant of the Cairnholy fields?
It would be nice if we/you/tiompan etc. could talk with that man.
Anyway, the latest find in Dumfries and Galloway was made by the farmer of Broughton Mains Farm; http://www.themodernantiquarian.com/post/30398.
He found the decorated stone in an old fieldwall and displayed it behind the gastank in the farmyard. As far as I know the stone isn't reported yet.
Take a look there when you go to Ayrshire, Wigtown or Ireland!
Have a great summer.
Cheers,
Jan
