All you need is a few dozen decoys, some portable marsh seats, and a couple of spinning-wing enticers. Set up in a line along the east side of a shallow-water impoundment levee, using natural cover to hide. Then spread the decoys down that line, leaving plenty of space between them. Teal decoys are ideal but not necessary, because the birds will decoy to any puddle-duck species. Place a pair of spinners in the middle of the spread. Ideally, birds will finish near the center, and everyone will get some shooting when they disperse after the first shots. But if one side of the line proves hotter, just switch it up.
