I'm trying to come up with a way of building a small campfire under a tarp. I've seen some ideas, but wasn't really crazy about any of them. What I have in mind is basically using 2 tarps to make an A frame with a little air space between them. Each tarp would make up one side of the A frame. At the peak, one of the tarps would go slightly above and past the other tarp, so from above, you could see they overlapped, but from one of the sides you could see there is a small air space between them where they overlap. It seems like that would leave a space for smoke to vent and would also keep out the rain out. I would of course use fire retardant taps, keep the tarps a reasonable distance above the flame, and keep the fire small. Has anyone tried this or does anyone has a better solution?
