Well I guess I'm a convert now towards eradicating the snakes. My wife's input is pro-termination also.

As these snakes are typically on or around rocks, I thought I would just attach a machete to a long stick and ace 'em that way.

But is there a type of ammo that would be safe when basically shooting at rocks?
