Martti: the black cobra was found just before the Namibian boarder next to Orange River. Regarding the place and the difficulty to find snakes there, I obviously compare with what I know and the place I know the best is where I live where if the conditions are right I'm 99,9 % sure to find snakes (and rather 10 than 1) hence the frustration of my Namibian trip. By the way, I confirm that I love your post already and I'm looking forward to seeing the 2nd part
Jeroen: there's indeed a good chance that it could have made a difference but the problem is that I didn't have the opportunity to use the car as our tents were on the roof and once in place, it was obviously not possible to drive anymore.
