Agreed on all the above; my trips are short and small enough that I do bag all the food items in odor proof bags and even store garbage on top in a trash compactor bag...BUT, my food plan usually involves no leftover food waste and no coffee grinds; at worst it's wrappers, napkins, and facial tissues. If it were otherwise, storing trash with your food might get, um, not so nice.
I also find an under-appreciated art is where to place the canister in consideration (C)...i.e., NEVER in or around the tent. So far I've been lucky enough to not had any run-ins, but I am always wary of a bear possibly batting the thing around, and I often camp near (but not right at the edge of) water...the last thing I need is my canister (I use the smaller BearVault) floating around, or sunken, out of reach, after a bear's batted it around.
So far I've had the good fortune of finding depressions, crevasses, and other features that wouldn't cause an investigating ursine to toss the canister into the drink. I've also decided to put bright yellow retro-reflective tape around the lid, so that it's easier to find in both daytime and dark in case it does get moved (or if I'm undercaffeinated).
