The pilings look old, do you know how old they are? It is strange to see a body of water without a dock. Where I live the docks are so close together it is hard to fish between them.
Sometimes you just can't figure out what to do with a prompt, this works.
Those dock pilings could date to the early 1900s. I've seen photos from that time period when every inch of our shoreline was lined with, basically, one big dock, all along the river and into the bay. The town was built for the timber industry; I'm guessing the lumber mills needed a large, broad platform to load from.
There aren't any docks left, just the pilings. They make for interesting photos.
