When I was a Girl Scout in the 1960’s, we stayed overnight in a shelter. We slept on bunk beds and ate soldier’s rations probably left over from Korea or WWII.
I went to grade school in DC and we did a lot of the ‘bend over’ or ‘run to the school basement’ drills. I had no idea people did them in other parts of the country until fairly recently.
That’s a Washington-centric mindset for you. : )
In Superior, AZ, the plan was to take the entire town of 4,000 into the mine 500 level with people bringing their own stash of food. Not real well thought out but even Phoenix then was not considered a real likely target and it is 65 miles away. The mine, along with its sister mine in San Manuel did produce some 10% of the copper used in the USA though. Now, with the mines mostly closed, Superior would be a good spot to sit things out.
