One surprising thing that will get the SD wardens hopping is reports of hunter harassment and they are likely on your side as the hunter. I ran into some road closed signs one year on county managed gravel roads in a couple directions. It effectively closed off a square of land about 1 mile by 2 miles. A hunting lodge had leased rights to all the sections in that area and decided not to let anyone drive through. Found out later the guides had set up the signs and were chasing down anyone that drove around them, often toting shotguns in hand. That had already had warnings for stopping hunters on public roads and right of ways previously. This stunt got him years of jail time and the landowner in trouble who allowed it to go on so no more hunting leases there. I drove through all the roads they built that are now county managed public right of ways. Actually saw very few birds as they still had milo, corn and wide shelter belts still setup but up far off the road.
