The bad guys cars wouldn’t work either.
Nobody’s would. So there wouldn’t be any trucks hauling food and supplies across the nation. What people have at that point in time is all they have. What happens when nobody has any food, water, or electricity, except those who have thought ahead and prepared?
And keep in mind that DHS has said that anybody who stockpiles food is to be considered a potential terrorist, even though out the other side of their mouths they’re telling us we should all “be prepared”. They’re keeping track of who has food and weapons. And I can’t remember the details but there’s some executive order that says if there is an emergency the feds can confiscate any supplies that individuals have stored up.
The plans have been progressing all these years and everything is ready. Any day now.
