I am reminded of a story about a German family (Jewish?) that saw the writing on the wall before the borders were closed.
Unbeknownst to anyone, the father liquidated the family business, sold the house and furnishings. He turned the entire lot into gold. And for a couple of days he spent his time in the garage.
The family went on a vacation to Switzerland, the border guards inspected the car, luggage and the family themselves, finding nothing. They proceeded with their vacation and the border closed behind then soon after.
The family reestablished in Switzerland, buying a house and starting the family business again. Seems the guards didn’t look too closely at the cars toolkit, which had a fresh coat of paint on it, seemingly unused.
The solid gold wrenches and such were all right there, strapped to the car, out in the open, right under a thin coat of black paint.
Today, who would have the foresight and ability to liquidate everything and run, just in case? Who would take that risk on a hunch?
