I took this about four years ago when I was in Ucluelet on Vancouver Island. It's a part of the Wild Pacific Trail that traces the coastline. It's a well-maintained trail with benches like this every half mile or so.
I was here in late August (or "Fogust" as the locals say) when a thick fog would roll in most afternoons. You could see it sitting just offshore, and then at the right time it would approach and before you could say Foghorn Leghorn, you were in it. In this image, you can see it about a mile offshore.
Benches or empty chairs in an image allow us to imagine sitting there in the scene. Our eyes follow the direction it points, similar to a leading line, only with a different device. When a photo makes us look in a particular direction, it has captured our imagination as we weave our own story in the scene. However, if it has thick fog, that would be something different entirely.
