I see 'Preparedness' in different terms I guess...
I didn't know I was a 'Survivalist' or 'Preparer' until recently when I was informed by a collage outing group that stumbled onto my place while shocking fish for a state count of fishes in a local creek.
They seemed surprised I was there, or that anyone could live there,
But when I was a kid, we had 'River Rats' that lived down here all over the place...
The state has pretty much had them locked up in old folks homes or they died, but I always thought they had the right idea...
------------------
Fist off, I'm 'Off Grid',
I don't buy water, I have a well and a lake.
I don't buy electricity, I have solar panels, both PV and Thermal.
The electric company wanted $118,000 to run poles/lines, and another $18,000 for the underground lines I wanted running to my house site, plus they wanted to plant a big, ugly transformer right out in front of my house.
I didn't have the money, so I started on generators, which got old REAL FAST,
Then I started with a golf cart and solar panels to charge it,
And things got out of hand from there...
I stared by sand/charcoal filtering then using UV light to purify my lake water...
When I had it tested, filters/UV doesn't remove farm chemicals...
So I drilled a well into limestone, had it sleeved down to limestone so the farm chemicals couldn't infiltrate my well, and now I'm good to go.
The well required MORE solar panels to run the well pump, and even though I have a hand pump, I'm not going to swing on that pump everyday at my age...
I plant WAY MORE garden than I need, can or preserve everything I want and sell/give away the rest...
I have a 'Cool Storage' ('Root Cellar') underground,
It's a 40 foot metal shipping container with drains around the outside,
Drains on the inside,
Coated against rust and vented to prevent condensation.
Cost about $2,500 to buy/install, but I did the drains, digging, ect. myself.
I actually lived in a 20 foot container when I first started out there, and that was an experience before I buried it!
Those things will freeze you to death in the winter, bake you in the summer, and are claustrophobic since you don't have any natural light!
I have a 'Real' job designing automotive parts,
But I make the land pay for it's self.
Decorative in the spring, day lillies, herbs, ect. come out of the green house and go into the garden as soon as it thaws,
Since I have the first ones around, They sell for a premium.
I plant a HUGE garden, can/preserve everything I have jars & space for, and the rest brings in some money.
In the fall, it's pumpkins, squashes, pop corn and 'Indian' corn which sell really well around here around halwoeen...
If the land is going to be here (and it's not going anywhere!) it's going to work for it's living!
I have fruit & nut trees, they are native spices, not the big 'Hybrid' types you see in the stores.
Lavender and even weeds sell to the 'Decorator' types, I can't see why anyone would want dead weeds in their home, but they sell REALLY WELL.
The barn/shed/workshop pays for it's self with machine tools and welding projects, and I repair vehicles/equipment that other people don't know where to start...
Plus I get to make a bunch of my own stuff, like my solar panel racks, greenhouse frames, ect.
I have a LITTLE house, and it's poured concrete, earth sheltered.
I believe that a house pays you NOTHING, and costs you money,
And if you don't lay on your backside playing video games or staring at the idiot box, you don't need a bunch of space to keep from getting clostrophobic...
If you are bored, go work in the garden! That will keep you busy!
I catch rain water off the garage roof and solar panels, and even in our 'Severe Drought Conditions' we have had this year, I still haven't had to draw one gallon of water from the well to wet the garden with...
I use a goat to 'Mow' what I have designated as 'Yard' and to keep the weeds down around the solar panels, garage, ect.
And the goat is going into the freezer pretty soon since his job is just about over for this year, and I'll get another one next spring.
Same with the rabbits in the green house.
Since CO2 the rabbits put off help the plants, they eat green house waste, put out a very good fertilizer, and wind up as meat in the freezer in the fall, they work out pretty good!
I try not to waste ANYTHING, my grandparents were depression era folks, and they wasted NOTHING, so I try to find a second or third use for EVERYTHING!
As for saving 'Junk' metal,
I have a fence row with several 'Parts' vehicles in it,
And I have several racks/bins with steel in them for fabricating things.
The only 'Junk Coins' I bother to collect is silver coins since I silver solder metal quite often and they come in handy for that.
What I stockpile is welding rods and mason jars...
If I can't build or make something from what I have around, it goes to the re-cycler. I don't want to pay for it to sit here if I'm not going to use it pretty soon...
Like I said, I'm a little 'Off', a screwball according to the neighbors,
But this spring, when the weather set the power lines to sizzling on the ground, I didn't know the power was out for two days after the storm!
No interruption at my house since I'm solar/battery!
