Interesting Perspective.

My view point is all this depends on what the emergency is, if you have any where to go, etc.

Id have enough stored at home and stay in place until its clear to leave. Where Im located the highways would be choked within hours. After that first tier of supplies fails which it will Id rely on mobility. However you can carry only so much food, fuel etc.All this would depend on having a piece of land with good soil to plant in and a water supply. When my meds run out Im done. I try and have 6 months of meds stored. Mobility in vehicles depends on fuel ? If Ive stored 4 jerry cans of fuel thats a full tank of gas along with whats already in the tank. That gets me from one capital city to another. Then it depends on taking from other vehicle fuel tanks and if the pump tanks can be accessed.
