I just want to add the warning that it isn't just food you have to worry about being securing from critters. Several times I have had sweaty clothing items stolen or chewed up at night by deer seeking them for the salt. Once, I had my socks stolen, my belt chewed in half, and my brothers backpack and boots chewed on, all at night while we slept (and my dog, who was in the tent with us, growled). We had left them around camp. Now, at a minimum, I keep my boots and socks in the tent at night. It's tough to get everything into the tent,though, so I take my chances somewhat with my backpack. I at least try to keep it in a garbage bag.
