2024 - Good morning, Afternoon, Night

I was walking in the woods, some years ago, and it was very foggy in the trees, whilst the sun had been shining when I left home. The closer I drew to the field at the edge of the wood, the thicker the fog was, and there was a lot of shouting and banging. I emerged onto a film set, men in armour on horses, charging across the field, between brightly coloured tents. There were women cooking who knows what over campfires and a smoke machine, blowing smoke across the field where it drifted down into the wood.
I ducked back into the trees and watched for a while. It was fascinating. Think it was for Dr Who or Torchwood. They film a lot of those series in Cardiff.
