There is a good chance that I will need this cooler to remain COLD for 7 days! I am doing the frozen jugs, but I am planning on topping them with a few blocks of dry ice to buy me more time. Speaking of the jugs, I am having a heck of a time with them splitting open even after pouring off a cup or 2 of water before freezing them!
I use plastic coffee containers. They dont split like milk jugs.
Looking forward to your report!
