It is hard to explain in words but here goes, we would usually set the Canadas in a line (not exactly one behind the other but kind of scattered) angling out on the downwind side of the blind. We stopped the geese approximately 10 yds. from the point we wanted them to land in front of the blind. To keep the ducks from landing short with other duck decoys or over shooting the spread, we would put the majority if not all of the duck decoys on the upwind side of the spread and sprinkle a few up toward the bank on that end, this would usually shortstop them on the upwind side. Since we had a permanent blind, we would have to play with the positioning because we could not move the blind to suit the wind.
