Distances are driving distances as measured from the White House in Washington, DC to the county as measured by Google maps. That mileage does not include distance shipped to processors and distributions centers, so the actual distance food has traveled is probably higher. If fact, because food does go through distribution centers, the distances below are probably the same in magnitude no matter where you are in the Greater DC area. Labels on food generally make no fine distinction between where a food was grown, processed or finally sold, so balance your knowledge of geography with your knowledge of what is in season and where crops are typically grown.
