No idea about that sorry! I'm in the frozen north of Canada now!
@ Sockstall. Driving up to Livingstone will be a bit tricky! Best thing to do will be to jump on one of the companies that flies up to Kasane daily. Wilderness, Safari Air and Mack Air would be your best bets for that.
Usually pretty cheap, then just get the ferry across the river to the Zambia side, and then a taxi into livingstone.
A few companies around there but if you are going to Zambia, you really need to head up to Lusaka or Ndola.
