JH makes some recommendations that I've also read in a hiker's howto book.
 odor proof bag
 eat before you get to camp
 do not cook - cold soak or similar
 keep the food close so a critter has to decide whether an encounter is worth it
 sleep in uncommon places and not shelters were animals have developed habits
 hanging a bag properly is difficult; if hung far enough away the critters will have all night to try to get to it (see #4)
Keep in mind that this is about hiking not camping. The hiking book made reference to getting into camp and going right to sleep. Then waking in the morning and getting on the road before stopping for the first meal. And taking a nap whenever you wanted. It was all about the hike.
