hope it is not too late to give info about the falls.
I have been in Zimbabwe in may 2000, the place is great, the people there is all right, so don't be threatened for what you read. Vic falls is almost the last place in Zimbabwe where the chrisis is not so visible.
I have heard witnesses about the white condition there, it is not good at all.
Anyway I have enjoyed my stay, in may the power of the falls is maximum...
ciao Filippo
