Only once, many years ago, when I drove to a motor racing event where parking was little more than a collection of fields. I parked next to a hedge and went to enjoy the event. When I came out I couldn't find my car.
As time went on it became progressively easier to find my car, because there were so few cars left in the fields. It turned out I hadn't parked next to a hedge at all, I was bang in the middle of the field. It was easy to spot my car even from a distance, because by then there were only half a dozen cars left in that field.
