Ex-land surveyor, and have killed 100's of poisonous snakes that got in the way of our work. Usually cottonmouths and copperheads, very few rattlesnakes. Walking over the floating grass in Goose Creek Reservoir, stepped on a cottonmouth's head and pushed it through the grass, and the next step I made forward, the snake sprang up about 5 feet in the air. We all panicked and sure enough, a friggin nest of about 20 cottonmouths all rolled up together was about 7 feet from the boat. That's resulted in calling it a day and going to have a beer.--- and forgot about the huge cottonmouth that dropped in the boat off a cypress tree while doing soundings in Little River, near Socastee. That was entertaining.
