It's a good job it was you that posted the pictures, rather than me. Otherwise the rock art expert would have flown into an apoplectic rage. A fully skilled drystone waller carries the skills that built Stonehenge, which must be irksome to 'armchair critics'. I'm the last one from a particular area, in the Pennines, and now there are just bodgers left.
Rock Art is pretty rare in Wales, so it should just be out there waiting to be found. When I talked about fully owning a find, with this one I should probably have said 'disowned'.
