I am working for development organization since 21 years in Africa, and so far never have the chance to work or just visit South Africa.... It will be for sure one of my next stop/visit in the coming year, as I followed a lot of interesting articles and news about South Africa, and the Country as a whole looks very beautiful and attractive. I love National Parks, and I know that's one of the very good african place to visit for a game tour ;-)
Durban seems to be a quiet peaceful place compare to Johannesburg or Pretoria, and definitively an attractive city to visit.
