20: Plan a detailed world trip

I LOVE the world, love meeting different people from around the world in their own home. Fell in love with the world during the 1998 (I think) Olympics when the ceremony consisted of displays of cultural heritage from the world and I resolved that I wanted to soak it all up, but as Jilly from Philly sings, 'when I was a little girl, I dream to see the world, but how could this be, me a poor black girl'. Well I've been SUPER, SUPER blessed and have travelled a little bit and got to meet some beautiful inspiring people in Trinidad, Niger, Nepal, Ghana to name but a few countries I've been to, but greedy for more.
I've always loved the idea of epic road trips across Africa, driving through the Sahel and across Latin America, so even if I don't aim to complete (and physically can't if I'm going to achieve my other goals) the trip during my 30 before 30 challenge, I want to have the detailed plans for such an endeavour achieved during the challenge. Love the idea of the map above save for the racist omission of Africa.
