Never had a bear in camp in Q, but have had issues with portage robbers a couple of times - those bears just know that there is food in one of those packs, in one of those canoes, and if they don't smellfood, they will keep looking anyway.

All good thoughts, starting with the basics of a clean camp.
I worried about the "portage robbers" my first solo, double packing leaves the food pack vulnerable, and taking the time to hang it, didn't seem very feasible.
 Being a inventive type guy, I bought a personal safety (jogger) alarm and adapted it for a pack alarm. As IC will attest, its very loud and shrill. At the size and weight of a deck of cards, its worth it for a little extra piece of mind. Would be good for emergency signaling device, NOTHING in nature sounds like that, so should attract attention?
Attached to the food pack, I can't imagine ANY critter being able to tolerate its high decibel screech right in its ear :o
 IF it could, it must be old and deaf, and needs the food far worse than I do ;D
