I was just too late to cross!

By the time I reached the position of the people in the picture, the strong side wind was blowing the waves across the causeway, even though in theory it should still be open for another twenty minutes.
Better luck next time!
The causeway was heavily damaged during last winters storms, a section about fifty yards long was swept away where the white van is in the picture, and replaced by poured concrete, with luck in time the original set stones will replace it!
It would be a shame to lose the wonderful look of the stone road...
