I went to Zimbabwe in January to see Victoria Falls. They are beautiful, the land is beautiful, the economic situation there is tragic.
ATMs dispense US dollars, because the local currency is worthless. If you buy something, you can expect the $1s and $5s you get back to be extremely worn and faded, but never torn, which I suppose is the result of a lot of very careful handling. The $10s and $20s are, on the other hand, pristine.
