RH - We have big black snakes that hang out in/near our pond in Mass. I know nothing about snake identification but someone told me they might be black racers. Sorry - I am NOT a snake person. I am scared to death of them; I'm sure they're (mostly) harmless but I'm still scared of them. This doesn't mean I don't think they have a right to exist and to live on the same property with me. I just really, really don't want to see them. I'm cool knowing there are snakes that live in certain places around my yard; I just avoid those places.
The snakes we have are uniformly black, no other markings that I've noticed as I've been running away from them.
