When I was a kid and my family went on a picnic to the mountains, we would load up our food in our trusty metal ice chest cooler. It was greenish, a little dented and scuffed from years of use. We had refined how to pack the most food possible into our beloved ice chest. We would freeze chunks of ice in ice-cube trays (metal one with removable levered dividers) and carefully wrap the chunks in layers of dish towels to slow the melting. Mom knew just how to layer and stack all the food so it would stay cold as long as possible.
We used that ice chest for years, and eventually moved on to coolers that were more efficient, but we often brought the old ice chest along for back up storage — and a memories of good times on past outings. Click HERE to see the newest ice chests and coolers available.
