Come on Zimbabwe is a complete mess! Just because the safari operators can operate, by virtue of their US$ incomes, doesn't mean the place hasn't already gone "South".

I have been there in 1988, 1994, 2002 and 2006 and been over quite a bit of the country. It improved between 1988 and 1994, probably because the black on black "civil war" had only just finished a couple of years before 1988. 1994 the place was doing quite well by African standards. By 2002 the place had gone mostly to a basket case. By 2006 it was even further down the drain. What it is like now I can imagine.

People with access to US$ get by, by using all sorts of schemes and convoluted trading and bartering. It would have massive starvation if 3 million people hadn't left to work in neighbouring countries. It probably has the worst inflation in history of any country IMO.

It will only get worse before it gets better IMO.

That all said, if you want to do a safari there and book with a good, well setup, reputable outfitter I would still do it myself if I had the $$$ to book a hunt. A tuskless elephant cow hunt would be great.
