Flares for signals and heat/fire
Seniorman that was a very good real life story of when a flare is important to have in your pack.
It reminded me of that "Somebody's Gotta Do It: The Real Survivor" Episode #4 where Mike Rowe is not afraid to air video of himself being taught and making several mistakes on how to use signal flares. I could not find the video of it online, it may be available if you have Video On Demand from your provider, look under CNN. But here is a link to the transcript:

Bottom line: as with all tools its a good idea to practice how to use them. Good way to start a signal fire or smoke very quickly when search aircraft are heard or seen coming or you need to get warm and dry quickly. Rubbing sticks deep under a forest canopy while a plane flies overhead would be discouraging, especially if that search pattern was not repeated for days. Or not being able to figure out how to light a flare or where you dropped the striker like Mike Rowe did. He covers serious issues in an entertaining way, and some silly things as well, but even then there is a real issue hidden under there.
