Arklier,
If you don't want to stop at McD's..... What I do is fill empty Gatorade bottles and 1/2 gallon milk jugs with water and freeze them. When I go out I toss several of them in the cooler. When I get back, rinse the blood off and back in the freezer they go. Works great, keeps the fish and beverages cold and never need to buy ice! Of course I have a pretty large chest freezer.
