It sounds pretty adventurous to me – how many miles is this trip?

_{P.S. I had to laugh – one of the sponsored links at the side of this goal was “transgender counseling”.}

I’ve done this a few times, also frequently while they were building the Trans-Kalahari linking Botswana and Namibia (now a good decade plus years ago). It is worth it I think to do at least once.
Now it would be quite expensive with the rising fuel (and other costs, not to mention the transborder levy costs in Namibia, Botswana and Mozambique) but I would venture a guess that it is much cheaper than trying to fly to any of these countries and a whole lot more fun!
