Copperheads freak me out more than rattlers.
They never warn ya.
Water moccasins are particularly nasty and I would hit one with a 410 the moment I saw one.
The neighbors across the street told me they've had copperheads in their house a few times.
I didn't believe them, thinking they must have been corn snakes, until I found a young copperhead at the curb one night while walking the dogs.
Stuff like that makes me appreciate those big black snakes all the more.
