You "need" either a boat or a dog to retrieve, part of their regulations, but it sounds like you've got that covered.
You can wade to set decoys just fine. One of the blinds, can't remember the #, is right on a point that drops quick so getting decoys out "just a little further" can result in a swim
It's a good hike to the south blinds so dragging a canoe or small boat is a definite "no go", especially on the way out ... significant uphill.
If you're planning on hunting the co-op let me know if you want someone to show you around, I'd be more than happy to do so
I don't have a dog so I'm at the whim of my unreliable hunting partner (aka my brother.)
