About Harvest has produced two very interesting short documentaries about the industrial production of berries. NJ's Red October tells the story of the introduction of water harvesting of cranberries. It is being shown at film festivals and private screenings for the time being.
The Mighty Humble Blueberry tells how Elizabeth Coleman White and Frederick Vernon Coville tamed the wild blueberry for commercial production. It is now available for purchase from Amazon.
