Careful where you put your hands

I went to milk Tanner last Sunday evening in her pen. She has twins but still had too much milk for them and needed milked down a bit. I caught her and put the halter on her, but she wouldn't budge, just shaking her head and grunting uh-uh. After struggling with her for a few minutes I looked up to see what she was looking at, and saw this pair of snakes mating on the side of the barn. So, we moved to another spot for our milking. I don't mess with rat or king snakes as they won't harm you and they keep the rats under control. But I did kill a pair of very aggressive water moccasins racing toward me on the pond earlier that day.
