It also stocks books, from illustrated folk tales for children to philosophical dissertations on mankind's origins. MAROPENG: Exhibits (with a popular restaurant on the top floor) and Sterkfontein caves where fossils have been found; http://www.maropeng.co.za. Located about an hour's drive from Johannesburg, over well-maintained roads. Rent a car and drive yourself, or spend a little more and hire a car with driver if you are nervous about South Africa's reputation for high levels of violent crime. __
