If things get really bad for an extended period, I'm not too confident about individuals, families, or small groups survivability out in the boondocks. Got a group put together for protection out in your well defended hidden bunker? How many doctors and nurses? Just what can they handle in the bunker?
And the list of point failures due to lack of skilled and trained personnel in small groups goes on and on and on.
I don't live in a city. I won't live in a city. So I don't have to evacuate from a city. Same thing with coastal areas. Earthquake prone areas, etc.
I live in a small town with relatives available. Agricultural county. Food. Fuel from biomass. Good hunting. Doctors. Not close to targets even if they are hit. Not close to probable likely targets. Far enough from the coast that even a monster hurricane directly hitting the area won't be catastrophic by the time it gets here.
So, I'm not going anywhere further than a relative's house to borrow some tool I don't have. Will probably still be able to work in whatever health care is available. I'll work for barter or even for an IOU of assistance as needed.
Nuclear plant twelve miles away. Early on, I'll be trying to organize for its defense, continued operation, and maintenance. Recovery will occur first in areas with electricity if the SHTF that severely on a widespread scale.
I'll stick with a small community that has the capability of hunkering down and surviving...as a community. Odds are much better for me and mine than hitting the road for some supposed sanctuary that is probably going to be inundated with very hungry and very desperate survivors from cities where it was really bad. Pretty sure the local NG unit can handle that. Won't have to drop but four or five small bridges to control access to the county by road.
My plan has more to do with getting back here if something happens while I'm away. My emergency setup is modular. Stage I is the vehicle supplies. Stage II is the mountain bike and trailer when it's apparent that Stage I must be abandoned. Stage III is the feet and carrying a ruck. A ruck is taken off from time to time. Stage IV are absolutely basic and essential survival items that can be carried at all times....even while sleeping. Just in case something happens that requires bugging out RIGHT NOW!...not even taking time to throw on the ruck Don't carry water beyond a Camelbak. Carry a Katadyn filter. Live in a very well watered area.
I watch current events closely. I watch weather predictions and trends closely. I adjust travel accordingly. In late August 2005, if I had been going to Texas to visit friends, I would have been heading west on I40 not I10.
Same as nightspots, I listen to news and scuttlebutt, I don't go to trouble prone places. Considering New Madrid fault activity, I probably won't head west on I-40 in the future. Won't see me on I-10 heading west either, if there's a tropical storm in the Caribbean.
I prefer not to hang out at targets...whether natural or perhaps a target for man made grief. The coastal areas and earthquake zones are uninhabitable territory as far as I'm concerned. I will visit the coast...dependent on the weather report, of course. I don't visit earthquake zones. Well, the 1886 Charleston earthquake was felt in this area. It might have knocked a brick chimney over around here. Hurricane Hugo was still raising Cain when it got this far inland north of here in South Carolina. About the only damage to houses was if a tree fell on it, though.
If you live outside of cities, away from the coast, and outside of zones that will probably be hit by strong earthquakes, you'd probably be better off staying put in an area where you can count on assistance from your neighbors.
So, I'll still be able to draw on the resources of this community. Pretty good supply. Good chance of retaining electricity for several years. Health care. Farmers. Mechanics. Machinists. Hunting. Optometrists. Hundreds of needed skills that I don't have to either learn, obtain the tools, or do without. Just ask around,"How can I get this done?" "Who has this for trade?" "What do they need?" "I've credit built up at the hospital and Dr. So and So's office, think they need health care or would like to open an account against future need?"
It's good to have somewhere to run to...granted. It's better to not have to run. Cities are dependent on the transportation net for food much less everything else. Small towns in agricultural areas are not if forced to be self sufficient. I'll stay in the small town. Rather than the mountain cabin, it would be a good investment to find a small town that's not in the evacuation envelope of cities and develop some connections there...enough to be accepted at need. Caution, simply owning a cabin and a small piece of property in the area might not get you past the roadblocks. It will depend on how many destitute refugees have tried to get in and what skills you can contribute to the community. Lacking desirable skills, it will be very important to have strong connections in that community...more important than owning property there. Lacking valuable skills or strong local connections, you might be handed more paper money than you paid for your property and told,"We just bought it back in accordance with county ordinance 52-338...now hit the road." Very good chance that the local militia will have much more-and heavier-firepower at the roadblocks than your entire group possesses...making your weapons a very poor choice under the circumstances.
Firearms and ammunition are good things to have in an emergency. In a SHTF situation, whipping out a community is going to heighten the odds of your survival tremendously, though. I'll take both.
As far as the "if I can't eat it, use it for immediate survival, or shoot with it...why do I need it?" philosophy goes-if things get bad and stay bad, items such as hand tools will be invaluable items for trade. Skill with those tools will be even more valuable. That anvil, hammers, and tongs plus the knowledge to use them to repair other tools could be your ticket to admittance to a sanctuary-and survival. I seriously doubt a self sufficient community will be interested in admitting you for your armament and ammunition.
