By the rude bridge that arched the flood, Their flag to April's breeze unfurled, Here once the embattled farmers stood And fired the shot heard round the world. — Ralph Waldo Emerson
Today, Massachusetts celebrates Patriots' Day. In towns across the commonwealth, crowds will gather for parades of marching bands, scout troops and public officials. In Lexington and Concord, Redcoats and Minutemen will reenact the events of April 19, 1775, and that legendary march to the North Bridge.
