Late response but I'll give it to you. All I hunt 90% of the time I hunt water is Mazonia. Most all of the regulars know me (my name is obvious to my username)
As far as the fog goes, whoever says it doesn't get foggy out there doesn't hunt it enough. Take this mornings youth hunt for example. I could cut about 10 yards of fog wit ha 2Million CP spotlight. I have had days in the south unit where the conditions were just right and the fog was being blown off of Braidwood and you couldn't see the bowl light on your boat going across Pondo.
Most of us that have a blind there will leave decoys out. Some guys run gang lines (risky), some run 3 to a tree, and others (like me) run singles. Depending on what blind you are at you can have from 3' of water to 30' of water in front of you.
If you have any questions about a particular blind, let me know I'll give you what I can....... in PM
