OK, not really, but I thought that may sound unusual enough to catch your attention.
Do you see that wire threaded between the fence wires? It looks as if it goes down into the ground? Well, it does, and under the ground, it's attached to a "dead man". In this case, a dead man is probably a stick or a broken piece of fence post buried in the ground.
It's used where the fence may have a tendency to pull up away from the ground, like in a draw or a blow out. The stronger the tension on the fence, the larger and more deeply buried the dead man will be.
In this case, it's probably not very big, and is used pretty much in place of an additional post.
So, there's your educational bit about the Nebraska Outback for the day.
Thanks for stopping by. The coffee is always on.
