Neighbors on either side of me are family, have other family a few miles away, many friends within a thirty mile radius, mom and dad and siblings only five hours away along with other family, but I'll play along. I guess we are talking TEOTWAWKI here aren't we? If the looters came infrequently (say one or two at a time) then hunker down with the food and fight them off. Thing is, they probably won't come just a few at a time. These scenarios are always problematic because it is hard to predict what people will do and how far they will go. Would it be like the movie Cyborg? Or Mad Max? Or Waterworld? Or The Mailman? Will there be hoards of starving "zombies" roaming the countryside? Will they be armed? Will people huddle together and form hunting and gathering communities? Will you have to give up some of your harvests to local bands of armed brigands (led by martin and ben just kidding guys)? What if you live near a large city? Once all the resources in the city are used up you could have hoards of armed looters sweeping by you as they leave the city en masse. Word of someone with food could travel far and fast. You could have hundreds of looters swarming you all at once. Even with reinforcements you could be overwhelmed.
Or would it be just a temporary interruption of services? Would order be restored? Could order be restored? Who knows. Even if you try to disappear into the wilderness there could be thousands of others doing the same thing. Resources worldwide would reach the breaking point. What if you were starving and came across someone with food and they wouldn't share. What would you do? Let's add to this a starving family. Spouse, child, parents, etc. What would you do? Sorry, I digress (what else is new). Merely rhetorical questions, no reply needed. It's just this kind of thing is horrifying to think about.

Back on topic, the question is do you bug out and travel great distances or do you hunker down closer to home? And what about the year supply of food? Hmmm. If you hunker down with the food and said looters swarm in it may be too late to bug out then. Even if you are packed and ready it may still be too late. You could be overrun in your sleep. Guards could be taken out. Who knows. On the other hand, as others have pointed out, if you leave the food behind and travel you place yourself among the looters. If electrical services are disrupted on a large scale then refueling a vehicle may be out of the question as well. That leaves you traveling on foot for a very great distance. Not saying you couldn't have extra fuel. But if you get 20 miles per gallon you'll need at least 50 gals of fuel to travel 1000 miles; more will be needed if you want an emergency reserve. If you have a 20 gallon tank (most don't with that kind of mileage vehicle) you'll have to carry 30 extra gals of fuel. That's six 5 gal jerry cans, more if you want a reserve. Guessing not much room for food and water, let alone other supplies like shelter and such. Just an example, you can make your own computations with your own vehicle (and that's assuming your tank just happens to be full when the SHTF). At this point neither option seems very appealing to me. In the end I would probably share the food with neighbors and other family (that's just my current nature talking), hide or store the rest, and either 1) hunker down in the mountains until order was restored or all the crazies with AK 47s and basements full of ammo wiped each other out; or 2) stay with family close by (ideally, all of us could gather at a particular place). Afterwards, if possible or practical, return home and rebuild. Hopefully we will survive and humane and civil relations between people will be the rule of the day.
