I live in a town, and I have no intention of building a camp fire, but I definitely keep fire-making stuff in my kit. I have survival candles that give off heat as well as light. I have a propane camp stove that I would cook on if I'm in my particular survival situation.* There are lots of uses for fire other than camp fires, even in a town.

However, don't discount campfires just because you live in an "urban environment." Assuming it hasn't all burned down from raging gas-fed fires when all the gas mains break, there'll be lots of building scraps laying in huge piles after the quake, and having a camp fire in a parking lot is a great way to fight off depression and cold. I recommend safely built and tended fires. They're not just for cooking.




*I live in the San Francisco Bay Area, and my expected disaster is an earthquake. It's my assumption that I'll be stranded a week with no outside help of any kind. I have supplies for the two of us for a month.
