They’re very rare and you probably won’t see one, that’s most likely a Eastern Hognose, or Puff Adder that just gave you a mild coronary.
They are also very beneficial in rodent control. Ironically the state is legally barred from spending money collected from hunting licenses to protect their habitat because they are not a game animal.
