Preparing for a ZomApoc is no different then prepping for any disaster. food/water, shelter, transportation, protection, emergency power.
I have canned foods, powdered foods stockpiled for any disaster. I can hunt and trap.
I have a well on site. It runs oin electric and i can rig a small wind turbine to run it if needed.
My home is made of stone and I can fortify the first floor windows easily. We also have 2 fireplaces and plenty of firewood.
We have a pick up truck and our cars until the gas runs out. Then we have 6 horses. I won't be taking horses to a zombie infested area. I'd more likely go on foot if I had no vehicle.
I have plenty of guns and I reload my own bullets. I have supplies to replenish primers and plenty of gun powder. Knives and I can improvise if needed.
I have a 6500 watt gas generator I can run until the gas runs out. It powers most of the house. Once that goes I can use the truck and car alternators and the generator turbine to build small wind turbines and power 12 volt batteries. The generator inverter can be used to convert from 12 volt to 120 or 240. Deep cell Marine Batteries are the best but car and truck batteries will do to run lights for a short time. Battereis is what I'd be scavenging for most. If you can get a big enough battery bank you can run a house on wind if you live in the right area.
I have transportation whether gas flows or not. We head to my dad's house or the inlaws. They are in very rural communities. They are avid hunters and are about as well prepared as I am for any disaster. I am not afraid to "rough it". I've been there and done that. I can make it in the mountains on my own if need-be. You do what you have to in order to survive.
The fact is I expect people to come to my place. It's not likely to be lost to anything but an earthquake and we haven't had earthquakes around here in.. Well I've never been in one in my 43 years.
