Hello Crackard 420,
A few points supporting what Mike Kunkel, Pinchel and Ship Wrecked have stated:
1) These guys are not "protecting" their "best spots".
a) This area is definitely part of the Turkey Point Company and other hunting clubs or owned by individuals.
b) This area is adequately posted with signs in the fall but you can hunt outside the signs.
2) Remember that you must be within 300 meters (metres) of emergent vegetation while hunting within the inner bay ... so this is an "open water" area. I suspect that this is the area that Ship Wrecked was referring to.
3) Periodically a small private part of the Turkey Point Marsh is for sale. I took a look at a "slice" of this marsh (about 100 feet by 1600 feet) a few years ago.
4) There is also public hunting along the North Shore from the west end of the Turkey Point Company to the mouth of Big Creek. However there is some privately owned marsh between Port Rowan and Big Creek ... watch for the signs that are posted in the fall and stay outside of them.
Hope that clarifies and confirms a few things for you.
