One of the advantages of having worked as a camp cook for an outfitter (many moons ago), is that cooking in less than ideal conditions means being thrifty and practical. A couple good dutch ovens and a tool box full of utensils and a grub box and a 10 gallon jug of water will get about a dozen people fed and cared for for about a week. Add to that a fuel supply (propane and charcoal if I'm lucky, firewood if need be), and a good cook can get by fairly well.

Figure that if a few hundred thousand pioneers could make it work crossing the country, then why mess with success? You aren't gonna be able to feed everyone, but if you want to do your share, then you could do worse than a couple good cast iron pots and a cooking grate. Besides, everything tastes better cooked in a dutch oven over a fire, dontcha know?
