Initially, SHTF - nothing would change for me because I live with the premise that it is going to happen, so I don't afford myself many luxuries - other then hacking into the neighbors internet... I have not tried Winlink - although I should, just to see what it is all about. Would be better to be prepared now then to wait until it happens and then try to set it up in the dark.
My battery bank would take care of daytime operations while the generator would do double duty at night, recharging the batteries and running the fridge and freezer.
The natural gas supply will continue as long as the pumping stations continues to run.
If I had enough garden hose, I could tap the local well and have a 50 year supply of gas - at no charge to me, since they wouldn't be around to monitor it.
The key is to build a natural gas compressor and do a full natural gas conversion to the family vehicle. Then all you have to do is drive up to the gas well, hook up the pump, fill the tank and leave. The most vital part then would be motor oil consumption.
With no new production of motor oil, the local supply would dry up in about a week and then the motors would only run until the oil got too dirty and then they would wear out, or if they ran out of oil, they would seize and blow up.
At that point, even dirty motor oil would have a value.
It would be a good prep to buy 50 jugs of motor oil and 50 oil filters for the truck, car, tractor, generator....
