If I’ve got ammo and you’ve got food... Well...

You die, or I die. I bought a gun first by the way, then I bought food.
But a lot of surburban types think the way you do, and that is why rural will work and surburban will not. After the first couple of weeks, surburban is going to be about the same level of population as rural without the support structure of the land to back it. Unless of course you eat long pig without refridgeration.
