17-Nov-2002 -- Although the site was quite near the National Road 1 from Cape Town to Johannesburg, stopping on the road would be dangerous, and I was not sure whose land it was on. I then saw a sign to Thornhill Game Ranch, which I visited, and got their permission to visit the site.
The lodge does appear to be a pleasant place to spend the night for travellers between Cape Town and Johannesburg. For anyone interested it can be contacted at P O Box 21, Beaufort West, 082 320 8186.
Walking to the site was mostly flat and not very interesting, and certainly no game! The actual site was near the edge of a large alluvial fan.
