I hope you are also loaded with food and water. If you live in the city or the burbs your water will go off shortly after the lights go out. If you do not have water stored up what are you going to use to cook all that survival food you have bought? Water and water filtration system are key to surival.
What are you going to use to cook it on? If you have a rocket stove which you can make out a #10 can and a couple of regular cans you can use yard twigs to create intense heat and boil water or cook food in a skillet or pan inside your fireplace. Very little smoke or smell.
First thing you need to do in this scenario. Be it an EMP attack, cyber attack, or an inside job, is to plug up all the sinks, baths and get anything that can hold water and fill them ALL up. All your pots, pans, jugs, gas cans, cups, coffee pots, vases, EVERYTHING fill it to the brim before the water turns off.
I’ve been reviewing water systems, and have read a lot of complaints lately about the quality of the berkey filters. I’m leading towards a katadyn, but I’m still not sure...
