Back in the late 70's early 80's I duck hunted a lot. I used Duck Commander calls in the flooded timber. I had a wader vest they sold called a back water bag. Duck hunting turned into a rich mans sport with out of state guys paying huge money to hunt the places I used to hunt for nothing. Game and Fish ended permanent blinds on the river. Finding places to hunt got harder and harder. I have not bought a duck stamp since about 1985. I know I quit the year steel shot became mandatory.
They should be able to get some good permissions I would think.
