On June 4-5, 1988, New Haven Connecticut celebrated its 350th anniversary with a marathon festival on the Green. The festival was called "New Haven Celebrates New Haven" and it was a microcosm of every neighborhood group, civic organization, cultural association, arts organization and political leader–condensed together. It began with a parade of neighborhoods led by Mayor DiLieto and Governor O'Neill -- and concluded the next evening with everyone waltzing together -- filling the entire Green. In between people got a piece of birthday cake from the satiric "bureaucratic cake commission." Over 200,000 attended during the two days.
