If there is any wind at all, geese will have to land into it. Set your decoys in a fashion that will give you the best shot knowing they will have to land into the wind. If they are high pressured geese, they will not want to land very close to the trees. Maybe you can get them with some good pass shooting while they are working into your dekes. I'm sure some more guys will chime in with some other thoughts. Good luck to you.
