- First, the fire should be in a very visible place, so that both the smoke and light it produces are visible.
- Second, the fire should be in a place where it won't get away from you. The middle of the dried grasslands on a breezy day is a very bad place to burn a big fire.
- Third, don't let the fire get so big that you cannot put it out with the means you have at hand.
- And fourth, think about contrast. Unless you have a ton of birch bark or fatwood, everything else you would burn in the wild will produce a white smoke. If it is a cloudy day or foggy, no one will notice your white smoke against a white sky. Throw a few ounces of motor oil or brake fluid, plastic pieces, or any other petroleum-based substance into the fire to produce black smoke, which is much more noticeable.
