I just thought I'd share a recent experience with frozen food. While planning a recent 8-day camping trip, I decided we would try to take all of our own food in order to avoid buying anything. (By the way, we tent camp and an electric freezer was not an option) My strategy was to do a google search and read other people's experiences. Low and behold, there weren't many but I did find enough information to try something out. We ended up purchasing the "Igloo Ice Cube." We lined the bottom with 7 large frozen freeze pillows and packed it full of food. I think there were 3 steaks, several pounds of hamburger, bacon, sausage and various other previously frozen food. I then added 30 pounds of dry ice on top (cold air sinks) and some newspaper to fill in the air gaps. Well, 7 days later the food was still completely frozen and only began to thaw on the 8th day. We placed the cooler in the back of the SUV and left the drain open (no need to worry about dripping water) and kept the rear window on the car cracked open (the CO2 from the dry ice can thin the air in a small space).
Anyway, this worked pretty well for me, although the dry ice was about $50. I would like to know if anyone else has had any experiences with keeping food frozen on an extended trip. I'm always looking for a better idea.
But the place which you have selected for your camp, though never so rough and grim, begins at once to have its attractions, and becomes a very centre of civilization to you: “Home is home, be it never so homely. -Henry David Thoreau (1817–1862), U.S. philosopher, author, naturalist
