back home we have 18 acres, plenty of railroad ties and old tubing combined with barbed wire would make a secure area. we'd fence off the house and lake. I have enough food, water and vitimans to last 2 weeks. I figure if I can survive 2 weeks after shtf I should have a couple spare boxes of ammo to buy a trade for a tank of gas to make it home. Otherwise it's 7-9 day on foot.
