I have been hunting the Columbia river around the Wenatchee area and have had great luck. But here in the last couple weeks I have gone from limiting out to watch 10,000 duck flight by at 80 to 100 yards away. All I can figure out at this point is either I need to bring a rifle next time, or learn to swim and shoot. The worst part about it is I have killed more duck standing in my decoys then I have in the blind. Any ideas on what I can try to get them to come in? I haven't been setting in the same area or hunting the same place more than twice.
