“Marijuana growing operations in Wisconsin, watch out: the U.S. Forest Service has instructed hunters to look out for fields in the state’s Chequamegon-Nicolet National Forest. In August, one fisherman in the state came upon a 8,000-plant growing operation worth $8 million. One Justice Department director explained that growers, rather than creating one large field of marijuana plants, now plant a larger number of smaller fields to thwart aerial detection. Police interviews with those who have been apprehended on growing operations revealed that most were undocumented immigrants.”
