Why is this important..because walk along the boteti now, and you will come across so many stone age tools, this was a place of great signifacnce in the past, in terms of stone age tools...and not so proliphic within the upper reaches of the delta....why settle down unless you have a reliable water source, look at the banks of the boteti, it used to carry so much more water..but all along there was a great tool making culture...just go down and you will find a crafted stone..
