Under light drizzle we went walking through marshes, beneath giant freeway bridges (I 355) and over the rain-swollen Des Plaines River. After crossing the Centennial Trail footbridge we had a look at the tug harbor run by ARTCO (American River Transportation Company). There's lots of activity at nearby NORAMCO, but those tugs appear to service a much larger area. Would be good to find out more. In the meantime the marsh plants grow.
