The take

This waist-high stone was set on April 26, 1751 to mark the Transpeninsular Line — the Calvert arms carved into its south face, the Penn arms on the north. It's the oldest man-made object on this stretch of coast, sitting quietly at the lighthouse's base. Cross the street and you've changed states; the stone has been keeping score for 275 years.
