Jim, Interesting about the homeless. I've thought about it myself. I haven't experimented with candles much but I guess as long as there is some ventilation for air you should be o.k. I think there is gonna be more of this in the future and people need to get over the Disneyland mentality. Don't get me wrong. I liked disneyland when I was able to take the family on vacation. But now a vacation would be out of the question. As far as found gear, the survivorman show, (when I had cable), would utilize whatever he had on hand. And that's exactly what the homeless learn to do pretty quickly or not survive. So, even though I like my few pieces of highly engineered gear. I'm happy with DIY.
