C'mon up andy! I'm gonna take Jason next season
It just depends on what you want to do. We hunt for the stragglers (tired ducks) and blast them when they flare in. Really you need a few bags of decoys and a duck call. Or you can go out and see where they fly into the channel and blast them from cover. Typically the start of the season is easiest but the longer the season the less ducks you'll get without cover/camo.
You'll just have to practice every year and pick up on where they come in at your area. the more you hunt them, the better you'll get.
