Wagon scenery

Do you know that feeling to go somewhere and all of a sudden be attracted to something although nobody around you can understand what you can see in it? It happens to me from time to time and then I take pictures I don’t intend to present anywhere as they would probably be seen as rather dull and boring. But I like them and keep coming back to them. Like this one with the wagons:

I took it during one of our outings many years ago and I still remember the place and perceive the beauty of those wagons, lined up and waiting for their moment of importance. The wagons look like anvils, don’t they?

BTW I’ve found out in a dictionary that I could say informally that I am on the wagon to express that I don’t drink alcohol. Have you ever heard this phrase to be used?
