Stan- we see the same scenarios here in MI- on the managed waterfowling areas- Allegan Todd Farm, Fish Point, Point Moullie, Harsen's Island and the Muskegon wasterwater floodings (aka- "The poop factory")You can bet your last $ that those birds know the boundaries of the refuge (no shooting) zones, and only a real strong wind and overcast day can maybe get them in range for you.
