Well, it's 5 rows of 6 turbines, so it's the Kentish Flats windfarm; you must be looking SE or NW. Sea is a funny colour, maybe pic taken up-sun, so looking SE from somewhere like the SW Barrow area?
Or perhaps that's all a load of rubbish......
Aaah. Just looked at the chart, 5 rows of 6 means you are looking WSW-ish or ENE-ish. But no land behind if looking ENE.
That's not sand is it? You aren't standing on the Pan Sand or the Ridge are you?! Sheppey etc in the left background.
