When I was in the navy and going to a technical school in Millington Tennesee in 1963, the city fathers of Memphis asked the base commander to put Memphis off limits to military personnel. He said he would get back to them in a month. The next payday everyone on the base was paid in silver dollars and that was a large base. Two weeks later he did the same thing. After another week he asked the city fathers if they still wanted to be off limits. When they saw the millions of silver dollars floating around, they rather quickly changed their minds. I would think the area around Millington and Memphis would be a good hunting ground for some of those dollars if you could find the right places.
