Today we are getting a first hand look at a marijuana grow operation in the northwoods which led to the largest drug bust in state history. Earlier this month, agents found 50-thousand pot plants at several separate grow sites in the Chequamegon Nicolet National Forest. Twelve people were arrested and charged in federal court with running a massive marijuana growing operation. Today, the media is being taken on a tour of the grow sites to see the damage. It's likely the pot growers clear-cut large sections of forest land and diverted water from streams to grow the plants. Kirk Parker has the story.
