I started wondering how we smell to bears as we walk along the path, even during the daytime. Was it safe to carry any food at all? I watched 4-5 YouTube videos on choosing an appropriate hanging spot for the bag and more knots to know (thank you Girl Scouts!) for tying the bag to the tree. There are also YouTube videos of bears going after canisters campers had left on the ground or inadequately hung. The bears are very persistent! They usually succeed in demolishing the food supply and teaching a lesson to the hungry campers.
