I watched an episode of the programme "Going nowhere slowly" that was aired on Sunday 9 September 2009 on SABC3. I recorded it as on the preview I saw they’ll be at Mountain Zebra NP and watched it last night.
They had some nice shots of the Park as a whole and also commented positively on the peacefulness of the surroundings, the good standard of accommodation and the friendly service.
During their drive through the Park they got out of their vehicles along the road to look at animals, at places where one is not allowed to get out of your car, but I assume it was all for the sake of good television, but it might put the impression forward that this is allowed.
On their drive one of these overlander vehicles share the road with them, and the crew made an interesting observation. Every time the overland truck came close to them the animals would run away. Even when the truck passed them you could see zebra etc running away. Ian Roberts said that it is clear that it is not a good idea to visit such a park with an overlander truck as all the animals keep far away.
Now to get to the actual reason for this post.
The crew went to a location within the park where they said no camera crew where before. They climb up a hill (they call it a mountain but they must come to the Cape if they would like to see real mountains

)
On top of the mountain was a chess board carved into a rock! This hill was apparently a lookout / observation point for the English army during the Anglo Boer war. The guys on the mountain got bored and carved the chess board, not to play chess with each other. No, they had the guys on the next hill do the same and by means of signalling with mirrors they played chess with each other! Apparently a farmer living in the valley below caught on to this and played with. And the chess board and other writing still looks fresh 100+ years later
