I am getting the feeling that many of the posters about the snake issue don't have a lot of livestock? While I am entirely happy to have kingsnakes & gopher snakes around, rattlesnakes are another matter. I have had several sheep bitten, & if they are pregnant, they will abort (I know this from experience - plus, snakes facinate sheep, & they all crowd around to see - can result in several bitten by the same snake). A friend's Angora goat that was nursing her 2 week old kids was bitten in the chest/neck area by a rattler, & died, leaving behind her triplets as bottle babies. I have also spent a lot on money on vet bills for dog bitten by snakes. If I find a rattlesnake, I grab for a shovel.
