Hi
I spent the bst part of 2 and a half years in Southern Africa, and would definately agree that it is a superb country to visit, such varied landscpes to exerience, game, dune, etc, etc.
I know Namibia and Botswana prety well and a friend runs a company that specialises in Namibia and Bots - he worked as a safari guide there for 7-8 year and even wrote the National Safari Guides course and exams - check out his site:
