I believe Americans are waking up!
I personally know of many friends that have shredded their credit cards and are in a cash n carry situation, and this is a great situation for them.
But they also lack in basic home supplies.... This is what people also need to understand, stock up on food and medicine. If a banking holiday comes around ( and it will ) have extra food and supplies for at least three days... just basic necessities will make your life easier and safer.
