For as long as I've looked at the "Africa" plate in the atlas, Senegal has drawn my attention, and in particular, that point in Dakar where the land stretches westward into the Atlantic, drawn into a point. It's the Presqu'Ile of Cap Vert, better known as Dakar, and it's as far west as you can go on the continent of Africa. It's the end of the world, or the beginning. In my imagination, Cap Vert was low and sandy, somewhat desolate, with broad, watery horizons on all sides. I was way off.
