Larry,
I live down here and will tell you:
1. Read the regs. Twice. Several of the WMA's have regulations that differ significantly from the "normal" regs. Go to the Game and Fish website and look at the free maps they have of the WMA's.
2. Read the boating regs and make sure you are legal. If you hunt the WMA's, assume that you WILL be checked by the wardens, State and/or Federal, and particularly if you hunt Bayou Meto. Don't cram 6 hunters, 2 dogs, 15 dozen decoys, guns, shells, etc. into a 12-foot boat and expect that it's okay because it's "just boot deep flooded timber".
3. Plan on burning at least one day scouting. And by "scouting", don't just go to where you hear shooting and mark the holes with GPS. Since you have to be out of the timber by noon, it will only be a half day, and I mean boat out of the water by noon, not pulling up to the ramp...you will get a ticket. And I would recommend you don't leave the ramp until after daylight. Green timber all looks the same in the dark....and 10,000 acres of green timber in the dark, well...
4. Speaking of GPS, take a compass in addition to the GPS. In thick timber, a GPS can't always get a good reading.
5. It will be crowded. Lessen the impact by going during the week to do your scouting and hunting.
6. Be damn careful. Do not go by yourself. Some of the areas around the launches and main parts of the bayous/rivers are dangerous if you don't know them.
7. Think about doing a walk-in hunt your first time; there are a few walk-in accesses at most of the WMA's if not all.
8. Most people down here really aren't asshole Bubbas, but everyone down here has been followed to shooting holes, had people set up within 50 yards, and had said people shoot the ducks on the swing as they were working. So, we can get a little reluctant; respect usually goes both ways, and people will be more helpful than you might think if you aren't trying to get GPS coordinates from them.
Most of this is common sense, but we sell about 80,000 duck stamps down here every year, and common sense gets left at the truck quite often.
Best,
Rick
