Back when the kids were at home and I did a lot of fishing with them we use to eat a lot of fish. In the hottest weather I use to take a cooler with one fourth cold water and the rest ice in the boat and used that instead of the livewell. The fish wouldn't stay alive but they would stay fresh and taste great. I don't like to see dead fish in warm water for very long.
I got a sister in Aberdeen and I get out there fishing now and then. We don't usually get to the river as there is great fishing right in NE South Dakota in the Waubay/Webster area.
Do you ice fish out there Ron?
