Johannesburg. Never before in my life have I seen so many fences and walls, usually topped by electric fences, and so few pedestrians. Strangely enough, there are very few parked cars. Of course I had heard that Johannesburg is plagued by high crime and serious socio-political problems. But, as I shall find out today, it is something quite different meeting people who grew up here and use art to discuss life in this city.
