I buy 1/4 cow and 1/2 a pig every year and store them in the big freezer. Propane stove, water heater and furnace. Lots of canned items in the pantry.
Everyone else have mentioned good ideas.
As to guns, yes, many. But I don't know how to skin a deer
And the above mentioned generator.
Reason NOT to have meaning:
-How often are you without power for a possible extended time? Hurricane/ tornado/ blizzard zones? Heck, even earthquake zones...
-How easy is it to set up electrical to run the whole house? I don't do extension cords all over the floor.
-Cost analysis. Generac's are nice "auto" start but expensive. There is the maintenance cost and time. A decent sized portable generator is much cheaper and easier to maintain, but the hassle to get it going.
-will it run my whole house? Mine is a 12k peak/9k running watts. Not huge and not small. A microwave is 500 watts. I have 2 refrigerators/1 deep freezer/240 amp well pump/not sure cloths dryer. It runs the whole house nicely. If a high load source kicks in, you can hear the generator moan a bit under the start up load then levels out. If all frig/frez/pump/miro/dryer/dishwasher all run...I am toast. So don't
It installed 15 solar panels that runs my house during the day. I am not sure if the power goes out if it will power the house. Thinking it won't because it goes through the meter. Gotta figure that one out...
