no I have not, that’s good info though and I will give it a shot. Is there a ratio of ice to salt.@DrDmoney, have you ever added a little Rock salt (ice cream salt) in your Yeti cooler? It will make it super cold, if too much, will even freeze some of your stuff in your cooler. We have 3 Yetis and go on extended trips in August and September. My wife always adds a little rock salt to them.
