Hi Gordon thanks for the reply.
Yeah I was trying to think of some magazines; somehow I think National Geographic is a bit out of my league at the moment!
But seriously, yeah I was thinking about taking the equivalent of Nikon's D300 that they have in a few years. I might need to take a secondary camera though incase something happens to the first.
I am especially looking forward to seeing Zambia for the reasons you mentioned, and South Africa aswell because it will help me decide whether I want to go to university there.
