WE have hunted there a few times. Lots of marsh! I am sure you could do a walk in, but honestly i'm not positive. We have hunted from boats with mud motors. Watch out for the fan boats! I had a bad experience with a few guys feeling like they don't have to use the canals, and just cut through the 10' grass, only thing that stopped them was a few gunshots before they ran us over.
WE will be up there lat october too, we will be bouncing between there and Lake Superior.
