They are endless and they are empty, but they are as warm with life as the waters of a tropic sea. They are webbed with the paths of eland and wildebeest and Thompson’s gazelle and their hollows and valleys are trampled by thousands of zebra. I have seen a herd of buffalo invade the pastures under the occasional thorn tree groves and, now and then, the whimsically fashioned figure of a plodding rhino has moved along the horizon like a grey boulder come to life and adventure bound.
