I've seen about a million posts on food / bear cannisters / PCT hanging method, so I don't want to belabor a point. But I don't understand the value of going to all of the work of locating your food away from you. Isn't the smell of food going to permeate your hands, hair, tent, and pack after only a couple of days? Aren't all of the shelters and campsites going to reek of the smell of food - at least to a bear? Can't the bears smell this from miles and miles away?
Do most people hang their food trash as well their food? What do you normally carry your food trash in? Ursacks and Opsacks? Or Ziplocks? Do most campsites/shelters have trees that are large enough / tall enough to hang food?
