Well for your plan, each individual needs to make up a plan.
Mine goes as shown, for what I know, I live out of town, so I will use my resources well. On my acreage, I have forest, so set up boobie traps. Also, incase of disaster, I take my 88 4Runner, stocked with food, clothing, fuel, and my weapons of choice: 2x Mauls (half axe, half sledgehammer), 1x Machete, 2x Hatchets, 2x Axes, 1x Propane fueled flamethrower and a makeshift cowcatcher that I will attach to the 4Runner. After I leave the once safe haven, I will scavenge for balistics, surviors and food.
Happy Hunting
