Look back at the article and you will notice the growth in Arkansas. Overall, those numbers don't look to large, but in actuality, most of the illegal growth is along the state's western edge where they are processing chickens and building the boom in the NW corridor. So that growth is confined to a narrow area.
That figures. Arkansas is one of the more corrupt states in the union. They gave us Bill Clinton. Some people think it can't get much worse, but it will if they continue to import illegal labor.
