A LOOOOONG time ago, there used to be a koi pond bridge near White Lightnin' that had a North Carolina sign on one side and a South Carolina sign on the other. It was near what is now the entrance to the water park area. That was back before smurf Island I think. Not even any water in that area now.
Unless I miss my guess, that was the only time the state line has ever been referenced beyond the front gate.
