There is a sign just outside the Royal Natal National Park, "Canibals", which I thought was a bar or something. It turned out to be a lot darker - the nearest village is called Amazizi or "The Cannibals"; named after a group of people who resorted to cannibalism in the time of Shaka. The story itself was unclear - were they fleeing Shaka's army or whether they themselves were part of Shaka's army.
Out guide for the San paintings was Mathiba, a young man from the village. He was a talkative guide talking about a number of things - from his parents (mother from Lesotho, father from the village), his love of horses, his job as a groom in Johannesburg, and his many ideas on rural improvements - most notably starting a library.
I wish him all the best, and if you come this way, bring some books to drop off.
