OK, I am new to this whole zombie apocalypse/survivor/revolution/natural disaster scenario
but I have just been thinking through the practicalities.
In my favour: we have 2 open fireplaces and a huge multi-fuel burning stove. The latter is linked to and can run the central heating but we would need electricity for the pump so that's a bit of a bummer. On the plus, we have lots of wood and access to lots more as we live within walking distance of open countryside.
I am pretty resourceful. I can knit and crochet, mend things. Dh has done a lot of DIY in his time. I know lots of old time crafts eg how to bottle stuff, make preserves etc.
Also, re water: if tap supplies failed, we have a stream next to our house. I don't like the thought of drinking from there, but presumably it would be relatively safe to take water from the stream, boil it over the fire, and then drink it?
So far, so good. I know for a fact that when the stove is going full whack, you can heat a pan of water on the top surface to boiling point, so I guess I could heat a can of beans for a nutritious meal.
We have a large garden. Nothing much edible growing in it now, but if I can get hold of seeds from somewhere, I could plant enough to feed us pretty much all year round. Well, fruit and veggies anyway. Give me some chickens and that would help...
The main trouble is waiting for that first harvest. In terms of food, and bearing in mind we would be on stream water almost from the off, we could probably last a week!
