Back when dirt was new, the adult leaders of my Boy Scout troop put a couple of camping trips together.  Looking back I am sure they did the best they could.
But we were always missing items essemtial to comfort, hygiene, eating well, etcetera.  I decided then to study up, make lists, and always bring a full kit.  I can remember several times when I was the only one with a match, a piece of rope, a knife, salt & pepper, tea, etcetera.  I shared of course.
Later I decided to graduate myself from Scouts and to hike and camp in Califria's Sierra Nevada mountains, often solo.  My survival, first aid, and everyday kits kept growing.
