Haven't hunted it but know some guys that do or have. If they do it like I have heard they are going to. I have heard that eventually they are going build blinds on each of the holes.
As it is right now, as I understand it, the drawing is like any other drawing area in the state. Once you draw you head to your hole, if the water is deep enough you'll need a boat then you have to drag it out there, unless there happens to be a road that runs close to some part of the hole. There are a ton of areas you can walk into. That may be different now since we haven't had much water this year. The key is scouting. Drive around see where the birds are mark it on a map. If it's one of the drawing areas hope for the best or try to find an open area that is near enough to maybe take advantage of the flight. If it is an open area then get there and hope no one else beats ya.
Like I said I have never hunted there, only talked to people who have. There may be someone that can correct me on some of this, but this is how it is to the best of my knowledge.
