We were not comforted by the owners of the citrus farm where we were staying in Addo, making remarks like "are you driving that route?" and "well, it's not unsafe, but you'll see for yourself". Well, we did see indeed. Taking heed of their other advice ("fill up on gas before you enter, close your windows, lock your doors, and do not stop for that 6 hour stretch"), we drove through a place that was different from anything we ever saw before. Transkei is the birthplace of Nelson Mandela, is black and very poor, with grassy hills littered by small huts as far as the eye can see.
Kids in school uniforms are walking or hitch hiking along the highway at any time of the day, making you wonder if they actually attend school, or whether their uniform is the only clothing they have. Most of them do have a smartphone, which must cost more than the hut they live in. And most of them are happy, dancing, singing and laughing along that same highway.
It was a strenuous and long 2 days of driving. Interesting to see, but next time we'll probably fly.
