Well my son talked me into trying one more spot. We walked back into some PLOTS land a little bit and saw a couple jump out of some bare black dirt in a big grassy area between cornfields, so we set up our decoys and waited. If my aim was a bit more true we could have had quite a few, but we only bagged one.
That was fun, they kind of buzzed in from all directions. Once we sort of figured things out we could kind of watch them come in. But then we would get focused on a couple coming in and then some others would suddenly bust over our heads from a different direction! Flushed three bonus sharptails on the way back to the pickup, but I had an empty gun. I was happy we were able to spend that time together and Sam's pretty stoked to try again tomorrow. He has to finish some homework though. A good motivator for him to get that done!
