I Keep on Fallin'

In Carroll County, Maryland a fall line exists that separates the Piedmont region with that of the Coastal plain. Rolling hills transition into sandy flat lands that slowly sink in elevation to sea level. Thousand of years ago this fall line is where the ocean met the continent... Carroll County (and Macon) was beach property once upon a time.  I lived in the Piedmont region where farming was common and Suburbs plentiful. The coastal plain was naturally more urbanized because it was easier to access in early American history. The movement of people out into the country came with the introduction of more advanced modes of transportation.
