It's only when the tides goes down that you know who's been swimming naked. --- Warren Buffet.
That's sound investment advice, and it also applies to many other things in life. After all, few things are what they initially appear to be. Just like the fish pens in today's postcard, just below the surface, they are fish pens no more. Enjoy.
(Pixel-peepers: At dusk, it's usually too dark to take any pictures, but it's plenty bright for silhouettes. Just find yourself the correct subject, something that is unmistakeable even in the dark, and you have a photograph worth keeping.)
