That's cool - I'd love to check out several of their national parks. I'm sort of into the Zulu stuff (Shaka is buried somewhere under Couper Street near the limits of Stanger, Natal). Also would like to visit Ranthambhor and Corbett in India. And the Gir Forest, with India's only lion population. Oh, and Tsavo in Africa. And Dudhwa, in India (Arjan Singh's "Tiger Haven")...
Nets or not, I wouldn't swim off Durban Beach. :-)
