At the risk of opening up a cup of worms.... Since gates have most certainly curtailed poaching via wheeled conveyance, wouldn't the same be true if boat landings were restricted. For example, how about the Park Service erecting large signs within 500 yards or so of the mouths of Forney Creek, Hazel Creek, etc., making public boat landings illegal? Wait, there's more... Ferry landings would still be permitted by licensed operators who, among other things, would be required to prevent clients from carrying on bait - or lunch that could be fashioned into the same. The signs could perhaps read... NO PUBLIC BOAT LANDINGS. STRICTLY ENFORCED BY DRONES.
