I Cover the Waterfront
It isn't the docks or the boardwalk always, or the tidy views of ships and boats and tourists and buskers. If when you wander to the edge you take a right and go on past the cruise ships you end up with the heavily fenced and security controlled Cunard Shipyard on your left, where the literal waterfront was, and on your right a rather desolate area where grains go round and round, invisible from the outside, and come out somewhere on their way to stomachs elsewhere.
