A foggy start

We had a good walk, but a very foggy start. Unfortunately we could hardly see the sea. It looks cold, but there was hardly any wind. We dressed to the occasion so we weren't bothered by cold.
I started walking for a while with my sister and brother in law. They walk more speedily than my nieces. So at a certain point I left them to join my nieces whose speed suited me better (still bothered with a cold).

We walked 13K today. Up north along the beach, back through the dunes.
