The season is definately crashing to an end. We have a few weeks left and it should be good, but we are getting close to it. This is my 3rd season waterfowling, first really getting after the field geese, and we did much better than years past.
My lessons for the year:
Get there early. We got beat to one spot in early goose season and since then have set up at least an hour before shooting time.
Getting to your goose spot early lets you shoot the first light ducks that come by.
Keep a low profile. We all have layout blinds and they are even too high a lot of times. We have started digging out holes to lower the blinds.
Shoot in front of the geese. I am constantly shooting geese in the body, not the head. I think their slow wing beat gives the perception they are not moving as fast as they are.
