I know its and old post, but...
We live in a rural area, the local community consists of about 350 people. The nearest gas station or store of any kind is over 10 miles away.
We have water stored (150+ gallons) and non-perishable food with a 30-year shelf life. Being rural, some preparedness is a way of life.
You don't drive home with the gauge on "E", you make sure you have extra batteries, fuel, water, etc. This is really hitting home with the recent power shutoffs by PG&E here in Nor Cal. While we have not been affected, most adjacent areas have been.
That might mean the nearest store or gas station with power is now 30+ miles away. It is better to have it and not need it vs needing it and not having it.
