The Gracke, still going strong

That's cool.

The amount of trash that ends up in rivers is really pretty amazing. Especially around urban areas like DC. You toss an empty plastic soda bottle into the street, and a heavy rain will wash it into the gutter, down a storm drain, and eventually out into the river. There, the wind blows it over to the shoreline, where it and a few tons of other slimey flotsam hang out forever, or until this guy comes and cleans it up.
