Excellent data, Compugeek. You are really living up to your name (and I mean that in a very good way). I had been considering using a cooler like that to store emergency food in my truck down here in Houston, but it seems it would only extend the lifespan of the food a little bit.

So now I'm picturing a modified cooler with an automated vent fan that comes on two hours after dark to flush the hot air out of the cooler...
