Crete,I have a brother in law that lives in that area and he told me that the ducks have been getting pounded in that area pretty hard since opener.My suggestion would be to get in the truck and drive until you find some birds that are not so decoy shy.Most of us are in a mid season lull right now where the locals are very scittish and migrants have not arived yet.Even the nodak crew had a tough go of it this weekend.If you can find unharrassed birds(very rare these days)any decoy setup should work.Good luck.Mallard
