Imagine one day that suddenly and without warning, every single vehicle in the United States built after the 1970s was totally incapable of running. No going up to the grocery store, in fact no more food deliveries by truck anymore to your local store.
There would be no trains, planes or buses running. Only muscle powered canoes on the waterways.
Imagine that there is no longer any electricity. You cannot keep your food from spoiling in the refrigerator. There is no heat, no air conditioning. No electric tools or appliances work. There is no way to pump water to your house, so you are also without water.
Imagine that there is no telephone service of any sort. You cannot communicate with anyone unless you walk to where they are. Which means, too, no computers, no internet, no cellular phones or iPods, no television or radio.
Your world is silent except for the occasional bird chirp or dog barking…which won’t last long with no food for the dog. Perhaps there might be human screams of hunger…or despair.
The country has been transported back to the stone age. Your ability to grow your own food is limited to your access to seeds and whether or not you get enough rain.
