The Organic Farming Reserach Foundation posted a nifty little map, showing the location of all certified organic operations in the United States. It also linked the data into Google Earth, so that you can zoom into your neighborhood. Not surprisingly, the majority of operations are concentrated on the West Coast, Upper Midwest, and Northeast. But these only refer to certified operations, so a tofu plant in Watsonville, California gets the same size dot as a 1,500-acre wheat farm in Montana.
