These are some good ideas, but how can you cook something without the smell luring unwanted, starving and potentially dangerous drones? When a person gets hungry enough, they will do anything. (remember the Donner Pass folks) I don't know how a person can safely cook anything unless they are way out by themselves. Canned goods, albeit heavy, are the best bet. You can eat them cold with little luring odor. Beans, vienna sausage, sardines and vegetables are what I have hidden..........
