Now is the time for a disclaimer ;)

I suspect Cliff is scrupulous in attention to detail. A bears nose rivals a dogs and if they can smell it they will get your grounded food more easily than treed. Keep in mind that however you decide to odor proof your food it must also be able to take the abuse of the trail. Unprotected ziplocks are likely to burst. Another reason I like the vault.

Perhaps if you like to eat fresh the foods that have the most potential for causing trouble could be treed. I still like the idea of as odor free as possible but equally important, IMO, is not using "the bear tree" that everyone else uses.
