Map of Industrial Farms by Concentration in US and Virginia

The organization Food and Water Watch has put out a map of the United States showing varying concentrations of factory farms. You can adjust the map to look at all factory farms, or individual types of factory farms. You can select by state for a closer look. Select Virginia and then click on the various counties to get specific information. A few clicks through there is also a page of some state by state information they have put together. I can't speak to the accuracy of all that information, but the map, and the updates are interesting at least.
