I am wondering how others pack their sleeping bag.I have always put it in a stuff sack in the bottom of my pack. It seems that many others place it unstuffed in the bottom of the pack and let other items settle in around it. If so how do you stuff it, rolled, folded or random jam?

On somewhat the same subject, where do you carry your food bag? I have been putting it on top but that is contrary to the rule of putting the heavy stuff low. The heavy low rule was fine when we carried tall heavy packs but now my entire pack is below shoulder height so it is not as critical.
