I don't hunt there anymore so have no secret spots to protect. Generally, it is like any other tract of public land. The harder spots to access are going to be the best spots to hunt. I never killed any "good" deer hunting there but always filled the freezer.
Some things you need to know. It is very easy to get lost in those swamps. You may even know exactly the direction your boat is parked but cannot cross the body of water between you and the boat. This is especially true coming in or leaving in the dark. Daylight makes things look much different. I carried lots of lost hunters out of the swamps. Second, there will be duck hunters in most of those areas. If gunfire at daylight, retrievers and people slogging through the mud immediately before you can see bothers you, then hunt elsewhere or during bow season only. Third, parking on the riverbank can be a big mistake. Yachts do travel the Tenn-Tom waterway & don't always care or notice the boat tied to the bank. They produce a large wake. It really stinks to return to your boat after dark to find it sunk.
