There are many valid points that people have raised. Obviously, cross-contamination is an issue. This is where I want to test this theory out. How much is too much, and at what point does this not matter? Can the bears detect the cross-contamination of a backpack, when the food is within one of these anti-odor bags. Yes, they may scenting, that is smelling in the direction of the bag, but they could quickly lose interest and move on.

If one of these bags is used in conjunction with a bear cansiter. It might reduce the chances of the bear finding it. If they can't detect the food located within the bag, then they might get discouraged and move on. Testing the ieda is the best bet to determine what works and what doesn't work. Anybody can say that it won't work and give reasons, but actual testing may prove new results.
