and how long do you shoot your starving neighbors and wandering mobs?
I’m sure you’re one of those guys with remote wooded acreage and a spring in a temperate climate, and lots of bullets
but the average suburban home or country farmhouse was never built to become a block house.
I know from my family pioneer history of 250 years ago what it took to survive when there were roving bands of people willing to kill you and take what you had. I am neither in a climate nor a setting where defending by siege is feasible
My worst case plan is to go on the move when necessary and to be able to carry with us what we need to survive until reaching a place that is safe, and/or to safely hide or otherwide dispose of what wealth we can’t carry until we can get back for it. That may take a while. No further details necessary in this forum
Yes, if you want to think this through you have to balance between “holding the fort” and “hunter/gatherer”. In real life some semblance of both would likely work best. A small enough bag of dimes to easily carry. Some ammo belts, with a variety of weapons. Canned goods for the home stand. Jerky and water purification for life on the run. Rope and a good knife for either scenario.
Have you considered getting your neighbors together and fighting off the roving bands of people who are out stealing?
