I write, sometimes, about "the plateau" on my blog. It is where my wife grew up (pictured), and where her parents still live. It is very arid, and trees only grow there because they are imports from Australia, or because they are specially watered. One sees, on the right, a large green potato patch, which is irrigated from a borehole. OBSERVATION: I might fortuitously have captured the hawk which has been stealing my father-in-law's chicks, at the top edge of the photo.
