Pebbles

I came across these pebbles on a beach on the Isle of Sheppey. It is a pleasant stretch of shingle with views across the muddy Thames Estuary to the North Kent coast. Unfortunately close by is the worst, most offensive seaside development I have ever seen and I've seen most of the coast of the British Isles in my lifetime. Much of the land it is built on was reclaimed from the sea - would that it would return.
