Modern Art?

We have a river running through town. The park where it runs through is in need of some TLC. Occasionally there is a grocery cart or two in there. This past spring, they dredged the river and built up its banks and removed a few. The portion of the river which runs behind the high school had this interesting creation. I don't usually take my camera when the dog is with me, but I was glad I had my cellphone. Perhaps this could be considered modern art. I thought the caption was the best part.
