Copperhead + Timber Rattler
We are lucky here in Georgia to have two of the best possible snakes you can have as an indigenous species. The King snake and the Eastern Indigo snake. Both of them are immune to and eat every single venomous snake in North America and neither is poisonous. The Eastern indigo snake is protected by local, state and federal law. Both of them get to be about the same size, roughly 10-12 feet long fully grown.
