Today I bought two heavy duty, but lighter weight than my Bear Canister, Ursack food storage bags. I also got liners that are suppose to keep animals from smelling what you have inside. The bags should protect our food from all the mice that visit the shelters along the trail. They are also strong enough to withstand a bear trying to rip them open. I have rope usually used for a clothes line that will also work when hanging the bags in bear country. I'll use "The PCT Method" to hang the bags.
I am confident two bags will meet our needs when I have to bring over 3 days of food for the four of us. We can also use them for storing toothpaste and othe scented items.
Next obstacle is putting together a rainy weather system.
