Whoa. The U.S. Semiquincentennial is only ten months away. I haven't done any planning.
"The plans for the Bicentennial began when Congress created the American Revolution Bicentennial Commission on July 4, 1966. Initially, the Bicentennial celebration was planned as a single city exposition (titled Expo '76) that would be staged in either Philadelphia or Boston. After 6½ years of tumultuous debate, the Commission recommended that there should not be a single event, and Congress dissolved it on December 11, 1973, and created the American Revolution Bicentennial Administration (ARBA), which was charged with encouraging and coordinating locally sponsored events."
