Butane lighters are fine in dry conditions, but are as useless as an ashtray on a motorcycle if they get damp. I carry stick matches, a magnesium/flint setup and use my leatherman for a stiker instead of my good knife. Then for the urgent needs, a road flare or two.
This spring I'm planning a fishing/camping/outdoor skills weekend for me an the boys. There is an island on Sginaw Bay I just learned is public land, isolated, has good fishing. We are going to camp and fish, and I can spend some time with the boys honing their wilderness emergency skills such as fire making, shelter, food and water etc. Should be fun, as long as the fish are biting, although if we time it right we should be able to get plenty of carp shooting in too.
