BTW, you better take some US $$$$ to Victoria Falls, my Brother in law went there for his honeymoon, they don't accept Zim$ there!! But then you always get a better feel for a place if you visit the local shops.....whether they have anything to buy in them is another matter.
I hope you make it, then perhaps you can play the, "Lets cross the Border to South Africa game"...which I believe you guys in the US also have a similar game with Mexico....around 1000-2000 Zimmers (not the metal ones old people use) sneak into SA everyday!!
