River Rubbish

Have you ever walked along a stretch of harbour and seen flotsam and jetsam trapped between pontoons or piles and wondered how it ever gets cleared? They say every day is a school day and when I was shambling along the clydeside today I saw this little barge with a hydraulic grab ramming into the large debris fields trapped at a pontoon, scooping up the rubbish and dropping it into a barge to be removed

There was a funny shot as the skipper of the little barge had his dog with him who jumped up onto the skippers seat when he stepped out the wheelhouse but I could not get the shot... I'm an amateur, I know
