NO NIGHT CACHING
The Mason–Dixon line was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon to resolve a border dispute involving Maryland, Pennsylvania, and Delaware in Colonial America. It is still a demarcation line between four U.S. states, forming part of the borders of Pennsylvania, Maryland, Delaware, and West Virginia. Informally, it was the border between the northern and southern states around the time of the Civil War.
The Jacobs Evangelical Lutheran Church once sat at this site.
The cemetery is in Maryland. Across the street, it's Pennsylvania.
