Hey sharp,
Another tip. Next time you go out there, arrive a little early and give your decoys a wipe down with towel that you've sprayed some WD-40 on. It'll help keep the water off em. Decoys that are shiney from dew or frost don't look right to the birds.

I've seen honkers flare off a set-up as they circled and caught the morning sunlight glint off some frost backed decoys. It happened three times, all when the geese got over the same part of the spread. A quick rub down, and the fourth flight of honkers finished up real nice.

Good luck this season
