I can relate to this.
I got bit by a cottonmouth in 1959. We lived out in the boonies in Annapolis, Maryland and one morning one had come up through the septic system and was in the toilet. Since I was a kid and dumber than a rock, I tried to fish the snake out. It bit me and I then got to find out about anti-venom shots, tetanus immunizations, and several other things that were unpleasant.
I was really sick for about a week.
“one morning one had come up through the septic system and was in the toilet.”
Not a pretty thought.
