Talk about pond water displacement. Bet it rises about 6 feet when those shaggy school buses wallow into there. I'm sure it's fun to watch them mess around in the water. I've always felt for any livestock, horses and wild animals that have to deal with biting flies. It would drive me NUTS. That was always a bad part of working in the woods, the flies. I still yell at them now and then when they bug me. Old habits die hard.
I love the rolling around in the dust. I'm sure it works, and feels good. I think that's why birds take dust baths. Hope your Sunday is going well, and not too many bugs.
