I had a great spring break trip to Colonial Williamsburg, Virginia and popped over to Yorktown and Jamestown. Among the ruins in Jamestown -- the town was largely abandoned after the capitol moved to Williamsburg in the late 1600's -- is an old church where a variety of commemorative panels have been hung including this one that stated that the founding of Jamestown marked the introduction of the common law to America.
My 2302's will soon cover the judiciary and with it an overview of common law.
