Thames estuary at low tide

Weather has been grey all day but not cold. No school today, back tomorrow. This morning I went for a walk with the U3A and had a great time, met some interesting people and had coffee too:) Arrived early and took some shots before the walk, just as well because I haven't been out since, have a really bad headache:( This was taken looking towards the pier (you can see the train) and the boats looked colourful. It must have been low tide because the sea was way out.
