Pat the first thing I thought of was a while back when DD1 Dave said. Hogs killed/reduced the snakes at this place. But I have only seen one hog in the past 2 or 3 years and I saw him a couple weeks ago on my neighbors place. I have had them in the past 5 yrs. It's easy to recognize if they are there. Going back to the no snakes seen at the pond statement, I don't know if it is due to years of hunting pressure on them or are they being eaten by the lmb?
Do not judge me by the politicians in my City, State or Federal Government.
