That's true. We had plenty of rattlesnakes in the area where we lived in Oregon, but we also had a bunch of goats and we never saw a snake anywhere near the house or barn. I've heard that snakes also don't like vibrations (which the goats' little thundering hooves provided a-plenty!) Wonder if those gopher chasers would work for snakes?
Confidence is that feeling you have right before you do something really stupid.
