Deep in the dense growth of a commercial forest there is a very old tree, half dead but still growing. Its trunk is about 2 metres across at the base.
It has stood for at least 150 years as it is marked on maps of a 19th Century hunting lodge. It must have been big even then, because someone nailed a horseshoe into it.
When the forestry was planted 30-odd years ago and the other old trees removed, this one was left alone.
The horseshoe is upturned, leaking out all it's good luck.
