Some people choose not to carry them, that's all. Some people love matches (raises hand), others hate them and only use lighters and spark-based ignition systems. I swear by nalgene bottles, others at them. There is no one right answer to gear selection. You take what you know how to use, like, and can afford. Every kit is a balancing act.

Flares would be great to have, but first I consider the extra weight, like anything else I tote. More importantly, flares should be stored correctly. They have to be to be in good shape when I would need them. That's something of a hassle for me toting my most commonly used daypack. Roadflares and such should be kept dry, because if the paper gets wet and the seal opens, the sulfur will leak out. The corrosives are hazardous to skin and eyes, I would have to go thru the trouble of having their own "special container," because they would contaminate many "more important" things in my little daypack if they leaked.. Precautions to keep them away from fuel and from anything else that I pack that’s ignitable in any way have to be taken also . I trek through heavy brush alot. Going thru that heavy brush knocks my gear around alot. I hope this makes it clear why they don't work for me.

Simon, good enough! I was just curious.
