Matches are a must-have in our troop. We have never had any real trouble with them, although a couple of years ago one of our scouts used his matches to light the spray form an aerosol can of bug spray (even though aerosol cans are forbidden at campouts). The resulting flamethower was impressive, but very dangerous. Besides the flamethrower danger, cans have been known to explode while doing this, causing loss of fingers & hands. We took away the scout's firem'n chit for several months, during which he had to give a class on fire safety to the entire troop. He was also suspended from campouts for a couple of months.
