This image is taken at the Belgian coast two years ago in mid October at low tide in the late afternoon.
When there is some wind, people get their sand yachts and race along the empty beaches. There are two kinds of these sport gears: one kind is similar to a sail boat like in the image above, while the other kind is pulled by a kite.
As I said a few weeks ago already, you can go to the beach in every season and find many different, but interesting, thing to photograph.
This is my contribution to Monochrome Madness organized by Leanne Cole. Look at here site on Thursday (Australian time), to see many more monochrome images created by many other talented photographers.
