Read the articles and saw a few you tubes on Cooladoors. Why I didn't figure this one out is beyond me but this is a superb application. I ordered a 120 qt Igloo cooler, clear un-sented water beads and a few find mesh food straining bags. All for 90 bucks and shipped via Amazon Prime to my house today; (2 day) There will be 20 or so boxes going into this baby tonight. I'm pumped.
