Around my dock/pier which is built from rocks, we have a bunch of water snakes. But man are they aggressive. You can throw big rocks at them when they're in the water, and they just move over a few inches and stare at you with their mouths open. They don't "run away."

I fish from there w/ shiners and minnows all the time so they wait around for a free meal. I guess it doesn't help that I throw them some dead shiners from time to time.

But to James, if you wanted him dead, you could also just use a higher powered bb/pellet gun if you still didn't want to use the .22 as suggested.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
