A storage yard on the Willamette River is filed with barrels that proved irrestible, so I took a picture.

I passed by this storage yard several times on my bike, along Highway 30, which is the main arterial serving the many industries that line the Willamette River in north Portland. Barrels are normally used for storing and transporting chemicals, but I had no idea what these were used for. I found similar barrel yards in Seattle along the industrial Duwamish waterway, in Seattle. (Click on the photograph to see a larger picture on a separate picture page.)
