Forget Idaho. County Super Spuds has been growing Maine potatoes for five generations. The company operates through three subsidiaries -- the 500-acre Sunday River Farms (bought in 2004) grows the potatoes, JDR Transport (launched in 1992) ships them to food processors such as Penobscot McCrum, which was also bought in 2004. County Super Spuds is owned by the McCrum family. The company is located in Aroostook County, in northeastern Maine near the Canadian border, which was known as the Potato Capital of America in the early 20th century.
