Updated: 12/16/2011 - Cory Ekum is talking cameras. Not for taking snapshots but special cameras he uses while hunting to track deer. "You can see what deer have come into the area, what new fawns have been born," Ekum said about trail cameras. He added they are important to use at night. But he can only do so on his private property year-round. That is because in Wisconsin, strapping a camera to a tree overnight is technically illegal.
