"You could always ride it there Jacq"

It would be one hell of a trip. It might be worth watching Ewan & Charlie's A Long Way Down from what I remember it was a similar ride. Take a spare couple of filters & some decent goggles though the top end of Africa is a bit sandy.
I know some people you could stay with in Zimbabwe to grab a shower & a feed.
Yup that would be a proper adventure.
