Under snakes There is a forum for this subject. "What's this?". Looks to me like a banded watersnake. It's definately no coral snake and is harmless. A trick you can learn the venomous snakes in your area not all the non venomous and by process of elimination you can tell if it's safe or not. There's always much less venomous snake species wherever you live in the USA than non venomous snakes.
