Late one night, our goats got out of the barn. I was a wakened by their barking protectors, our Great Pyrenees dogs.
I ventured out into the darkness. in my PJs. I found the four animals behind the barn (very dark behind the barn) and started the roundup. I did not see a three foot steel corner part of a fence. I fell into and over it and proceeded to roll.
My accident occurred becasue I was walking in the dark. If I was walking in the light, I would have seen the obstacle and avoided it, the pain, and aggravation that followed.
