“There being no direct route to Savannah from Charleston, I followed a zigzagging course that took me through the tidal flatlands of the South Carolina low country. As I approached Savannah, the road narrowed to a two-lane blacktop shaded by tall trees. There was an occasional produce stand by the side of the road and a few cottages set into the foliage, but nothing resembling urban sprawl. The voice on the radio informed me that I had entered a zone called the Coastal Empire.”
