Well that's not something you see very often on the Essex/Suffolk border ...
Had a nothing day for photos so drove into town to see if anything on the 'beach' caught my eye ... Lots of photos of boats, chains, tide times board, boat yard and almost missed the seal splashing about in the mud!
Took a few shots with my 18-55 lens, then dove into car and nipped home for my telefoto (As I had decided when leaving that I didn't need it ...). Got back in time to see the seal swimming off into the Stour.
