There are blinds. You are required to hunt within the blinds. Most blinds require a walk through water so waders are needed. Some are pit blinds below the ground but most are above the ground welded metal blinds with grass camo. If you have a dog, something to put on the floor to keep them from getting to cold would help.
You meet at the HQ (early) and draw a blind. Then you pay for hunters, get a map to you blind and head out. Pretty simple.
They normally don't walk up to the blind and surrender.
Not every blind on the place is a barrel melter and the birds will move around as pressure and food dictate. There's no such thing as a sure thing anywhere but they have come a long way in making for some good duck hunting.
If I knew where you were coming from I could give you a little bit better idea of what to expect vs your home turf.
