Beowulf,
We only have one "nasty, bitey snake" in my neck of the woods, and it's pretty shy. Not like out in the West and South where they have all sorts of nasty poisonous varieties.
Still don't like them, whether they bite or not. Yucky old slithery things.
As for "puppy eating snakes" those can stay in the Amazon jungles where they belong.
