It's a long response...post up if you get drawn.
If you draw magee you need a dog.
I should clarify - the grass in the marsh at Magee is very thick and very tough. Unless you get a perfect day of uneducated migrators the birds are pretty spooked and will decoy a little but not commit. As a result - people sky bust. Then others start to sky bust and pass shoot. Then you end up with a lot of woundies and when they swim into that marsh grass you can forget it without a dog.
If you can drop birds in the dekes you are OK. But that, in my experience, is tough there. Make sure you waterswat crips even though you have limited shells. I've heard people complain about only having 25 shells - thank God that's the case. If you aren't getting near a limit at an average 4 shots per bird...you're either a really bad shot or you're shooting at birds you shouldn't.
