When we stayed with Craig Watson, my father-in-law, we went hunting stone tools around Philippolis, Free State.
He has a great deal of knowledge of these tools and used to go collecting them with his brother Lyall Watson, the author of Supernature and numerous other books.
These tools were made and used by bushmen and can be found on the surface near rocky outcrops. It was great fun hunting for them and gave me a buzz finding something last handled around 70,000 yrs ago.
