Great thread Antar! some good suggestions here. I keep
seeing the subject of heirloom seeds coming up which is
excellent - there probably is no more important thing to have
besides fireams and ammunition.
I would add that hand powered tools are also a must; bowsaws,
axes, chisels, planers, drills, hammers, wrenches etc plus nails,
Wood will be critical for heating and suburban areas can provide
a fair quantity of it. Chainsaws will quickly run short of fuel so
their usefullness would be limited.
Fish could be farmed in small ponds if people were to dig them
in their backyards.
Survival foods may be critical anywhere you are - many weeds
are edible and quite nutritious including dandelion, plantain,
chickweed and others too numerous too mention. In virginia
where I live they can be had year round.
If protein runs short theres always earthworms, crickets,
grasshoppers, larvae of all sorts and most beetles. In addition
rodents like mice and rats can also be eaten if well cooked to
destroy hantavirus (handle them with gloves and face mask, HV is airborne).
As for protecting crops/gardens you can rotate watch, chain
dogs nearby or just set up trip alarms. Your alarms can be rigged
to make noise (or worse) whichever you choose.
Water will be an important factor and we must rig methods to
collect rainwater and dew. Failing that you can usually dig down
deep enough to hit the water table and make your own well.
Great thread and I hope to learn much more from others. Best
of luck to all!
