Hiking: the Mason-Dixon Trail
Our excursion took us to the Lock 12 Historic Area along the Susquehanna River in York County, Pennsylvania. We had passed this site many times on our travels, so we finally decided to stop. The lock was once part of the Susquehanna and Tidewater Canal, which was built primarily to haul coal, lumber, and other goods from central Pennsylvania to the shipping ports of Baltimore and Philadelphia.
