Stiwdio Maelor

I'm now on my third day as "Visiting Artist" at Stiwdio Maelor, and settling down into the village - getting to recognise faces in the street, and becoming a regular in the pub (for the Wi-fi) which is, in itself, a new experience.
The village had its' heyday in the 19th and 20th Centuries, when the local slate mines were at the peak of their production.  Slate is everywhere - in the houses, the bridges, the gardens and the fields.
I'm intrigued by the initials carved into the parapets of the bridges: layer upon layer of carvings, some over a hundred years old.  No recent ones, or at least few after the 1960's:  children nowadays don't carry a pocket knife.
