Employees at the Chequamegon Nicolet National Forest spent this week cleaning the mess and destruction left behind in Wisconsin's largest pot bust. Forestry workers spent time this week cleaning up the grow sites that were home to about 50,000 marijuana plants. With it being a multi-year operation, a lot of trash was left behind. Now it will take years for the forest to naturally grow back on its own. Plus there is concern the groundwater may be contaminated from the fertilizer used to grow the marijuana. Kirk Parker has the story.
