This spring will be the first time I have hunted snow geese. I have 24 shells, 12 northwinds, and a flag. I know this isn't much but that is all I have since I am just getting into it. How should I set the decoys up? Should I mix them all together, group them in 3's, in an x pattern, etc.? Should I lay in the middle, downwind side, etc.? Thanks for the help.
