I just finished watching it with my wife. It's amazing.
A couple quick comments:
-It is surprising how many other overlanders are also doing a similar journey even back then. They have a convoy with a Unimog with a map of the world on the side of the camper...things have not changed that much! And they are fascinated with the couple from Holland with their tiny car...pretty funny!
-We have been to several places mentioned in that journey - the Central African Republic, Lake Kivu/Goma in the DRC, Harare, etc...not much has changed since then. Actually in some ways these places are more dangerous, less developed than then. It is a bid sad.
-I am curious as to what is the current situation on the Trans-Sahara, especially the border crossing between Algeria and Niger. I have not heard of any overlanders going that way in a long time, but this documentary renewed my interest in that region. Hopefully we will have the chance to go back one day.
