Aitkin County Sheriff Dan Guida leaned over to politely ask Joshua Roy to move over to the side for a few moments while the Line 3 workers flattened a chunk of land nearby, Wednesday, Dec. 9, 20290, in Palisade, Minn. Protestors have been gathering for multiple days at a Line 3 work site near the Mississippi River in Aitkin County. A pair have even set up camps in the tops of trees on the work site.
