My Mauritanian friend gives me some cash to catch a “sept-place” private taxi to the border with Senegal. I catch it somewhere in the outskirts of dusty Nouakchott and receive honest treatment from the taxi operators. It is not too far to the river Senegal and the border, and the scenery is already getting richer. Some brushes, even trees start lining the road and by the time I got off in the village of Rosso the desert was behind me.
