A close look at the history of the once vitally important D & R Canal (Delaware & Raritan), built in 1830 and shut down to commercial traffic in 1932. The canal continues to be a historical and recreational gem. Narrated by Jean Shepherd. The documentary was produced in 1974 by the "Crossroads 76" production company. It was in the archives of the NJ Public Broadcasting Authority where it was digitized for preservation.
