Mozam, Malawi, Zambia, Tanzania, Kenya, Uganda, Rwanda, Angola, Namibia, Botswana, South Africa trip

Hey guys

I'm overlanding in a Landcruiser for 2 months on a round trip starting in South Africa in 2011
Any "must sees" in the above-mentioned countries that you guys really enjoyed? I'm particularly looking for unique adventure experiences!

Thanks
Over and out! :-)
