September 17 is Constitution Day, commemorating the day in 1787 when, at the end of a long hot summer of discussion, debate and deliberation, the delegates to the Constitutional Convention signed America’s most important document. George Washington, on behalf of the Convention, transmitted the proposed Constitution to the Congress assembled under the Articles of Confederation.  From the Preamble to the Presidency, from slavery to the Fourteenth Amendment, examine our most important and argued-about document.  Free pocket copies of the Consitution will be available for participants..  Registration Required.  Adults.
