re: I don't understand the obsession with the Yeti ice chest.

This^^^ I was coming here to post about extremes. I have a regular igloo and an extreme. I kept a pig in the igloo and changed the ice daily last week. I finally butchered it and put it in the extreme with a new bag of ice. 2 days later, the ice had barely lost anything to melt. I had forgotten how well it worked until that back to back experiment.
