Only tactic going to change is locating birds. This time of year is alwasy good because the congregate in larger numbers to keep water open, so the key is to find what body of water they are keeping open including rivers. Once you locate the birds, you can follow them out for spotting field shoots. This time of year is by far my fav and yes it does get chilly. you have to be smarter with your decoys and blinds, they have been shot all fall so they are definitely wiser but no funner time then to be out there. Looking forward to December duck shoots
