It is always a good idea to have provisions set aside for emergencies. Clean water, canned food, dry goods, medicines, bandaging materials, herbal remedies, candles and oil, flashlights and batteries, pet food etc. I lived in earthquake country for 35 years and everyone (most people I knew in SF) kept supplies of emergency goods. Rotate them regularly.
There are other options available as far as community goes. Please check out Transition Towns : this from Wiki:
"A Transition town is a grassroot community project that seeks to build resilience in response to peak oil,[1] climate destruction, and economic instability by creating a local group that uphold the values of the transition network.[citation needed] Local projects are usually based on the model's initial '12 ingredients' and later 'revised ingredients'.[2][3] The first initiative to use the name was Transition Town Totnes, founded in 2006. The socioeconomic movement is an example of fiscal localism.[4][5] Since then, many Transition groups have started around the UK and, in recent years, the world"
I was a member of the TT in Vancouver B.C. for 4 years. It is composed of 22 neighborhoods or 'villages' where accessing each other can be done on foot or bike if need be.
They are a vibrant group - teaching each other to plant food, harvest, can, save seeds, maintain bicycles, support for solar, greenhouses made from scrap materials, working with local gov't to reduce waste of resources (including gardening co-ops all over town), teaching permaculture, forum for visiting lecturers/teachers, bee keeping, small animal husbandry (allowed in Vancouver), candle and soap making, sewing and fabric creation... Some locations are trying to build local currencies where barter can be supplemented with 'tokens'. Here is their website to give you an idea:

Here is the main page for Transition Towns (Transition Network) which has locations all over the world:

It is not a spiritual movement but I had many deep spiritual discussions with various members. Facing the world we have been handed/and/or/created, unless your heart is dead, you will be having these discussions! We hosted Nicole Foss of the Automatic Earth in 2011 who covered energy issues and the goals of sustainable communities.
I wanted to add this so that anyone facing decisions might want to check the TT site for location info under Community tab. Maybe where you live now or plan to move to, already has a TT developing. It is a way to deal with the physical needs of a global descent. A self-sustaining community.
Goyacobol - I got a kick out of your name! I knew what it meant immediately... nobody would use COBOL but one of us old Cobol programmers! It was a great living and I loved the purity of programming. Only job on earth where you can achieve 100% perfection perhaps!
