Ruined rings

Bringing in more cattle today. Sorting them out was even more fun than usual as my back went "ping" this morning ,as I coughed while carrying a bag of barley.
Now crawling round like a half shut knife. Thought I was getting away with it this year! Ho hum.
Spotted these old ring feeders at the back of the dyke. It's easy to see which direction is North by the way the moss has grown on the bars.
