Would this man-made crop circle be appropriate for this challenge? With the roughly hewn cross at one end, it seems like a form of directional signage to me.
Now this photo below fits the bill 100%. There’s a bridge in the background and in the forefront we have a pier with a dock. Just look at that wonderful boat! Wouldn’t you love to hop in and go for a spin on the Chesapeake Bay? Some people have all the luck.
