I have to be careful here as John Dinardo has written a post with this in mind however this subject is one that a few lines will not suffice to do justice to it.
It is something i have given a lot of thought to, for a long time, not too deeply but have born it in mind . For myself I am in the position of the lone male with few if any attachments and can quite easily take to the open road if all hell broke loose in the planet X scenario. Others have options quite a lot different . Families, ill health, old age etc.However, i hope to bring up some ideas as for food, shelter, wind protection etc etc for all of us as we will need them at some time.. There may one or two errors, , please correct any I make. Beside being a worthwhile exercise for myself, I hope it will encourage others to think about this and at least have a bases for self protection when events get serious.
I have said elsewhere that the first and foremast preparation is spiritual preparedness. I cannot overemphasize this enough. Start here the keep going.I am not going into religion as I have none, save life itself which is sanctified enough and we need no more than that.
So assuming this base is covered, what then. The basis of all life is water, I have said elsewhere about making a water filter using charcoal and sand and gravel. The first thing we must do is have at least one maybe several water butts connected to the drain spouts of our home and any outbuildings as they do in Australia and the water is quite drinkable believe me.. They store water in huge vessels connected to most country homes, if you can afford it think about this.They are several hundred gallon capacity. It is clean fresh and tastes great.
However we are thinking here about a cataclysm where not only volcanic ash and such but possibly debris and chemicals from outer space. Plus there may be a lot of pathogens in the air and mold which is why for me this water we collect is not guaranteed to be readily drinkable. It may need filtering and purifying using bleach, plain sodium hypochlorate will do, or similar. Just a few drops per liter then let the water stand so the chlorine can evaporate.
One person today on coast to coast says we should store water in smaller bottles as the opening of any one will introduce bacteria , this makes no sense to me so long as we add a few drops of bleach or similar every time and allow the chlorine to evaporate. It is a matter of choice and what is available.also he says store it in a dark place which makes no sense to me as sunlight will help sterilize it in about six hours. These must be thought about.
this blog sums up my own increasing understanding of getting prepared.
