Several years ago we got off a plane and drove our rental car to a Sarasota Walmart. When we came out there was a yellow spray painted dot on our rear bumper, right side, about the size of a silver dollar. There is no way it was an accident. Yep we looked like tourists straight off the plane in a rental car. Our bags were in the trunk, but of course the inside of the car was pristine. Once we got to our unit, nail polish remover took it off. I have searched for years to find out what this was about. I believe we were targeted for something, but I don’t know what, and it never happened AFAIK.
