All smellables should canistered or hung. What is a smellable? It is anything with an odor that a bear might investigate, even if after investigation the bear would move on. That included water bottles that had Gatorade or equivalent in them, clothes worn while cooking or on which food or Gatorade spilled or dripped, toothbrush, food wrappers, etc. Putting food in the canister is the first priority, then toiletries like toothpaste, and then probably food wrappers. In a ideally clean bearproofed camp there will be nothing for a bear to eat, and nothing that entices the bear to investigate. There are at least two goals to serve: one is to deny reinforcing bear investigations of human campsites by eliminating the chance for the bear to find food, and the second is to avoid interaction between the humans and curious bears.
