It was closed. My usual luck. Too early. See the morning sun reflection? See my long shadow? See the cleaning lady's broom? She was inside on her hands and knees scrubbing the stairs. Really. But I wasn't here to go inside. See the small white square to the right of the entry midway up the wall above her broom handle? That was my objective.

Here you are. That nail head.
Why thank you. Your welcome.
