Finally! An awesome route! Haha screw Tar 24
So from my understanding, legs 1 & 2 are in Siem Reap, leg 3 is in Phuket, and leg 4 is in Namibia. I personally think that leg 5 will also be in Namibia. One leg could be on the Skeleton Coast and the other in a type of safari leg, such as Etosha National Park.
Also, I believe Namibia is going to be the only African country visited. After this they'll probably go up to Europe and from there to the Americas.
