I'm off to South Africa at the end of August for a photographic trip
Graham,
Have you read up on the crime situation in RSA? Please do yourself a favour and read extensively about the crime that is out of control in RSA. It's a very very violent place these days - it comes out of nowhere and hits you when you least expect it. I expect you will be in the hands of local tour operators and such, so they are of course aware and take precautions.
I am 2 countries North of RSA and we just dont go down there anymore - way way too dangerous now. If you want some truly horrifying stories to read, just google RSA farm murders. Its spread into the cities now too.
South Africa has STUNNING scenery - it's a beautiful place, but it's become a no go zone.
I tell you all this because we need you here, so read up and be aware. That's the best way to protect yourself in any situation.
Re the airlines here - it's still fairly lax. I even flew from South Africa to Zambia with a destroyed passport - try that in the western world and see how far you go (or dont go)
