In yesterday's post I asked a question about the direction in which I was taking the photo. Trust an engineer to work it out first - although I guess it would be fair to mention that Duncan knows this particular road pretty well. :)

So yes to all of you who agreed; from this shot (taken a little further on) you can easily deduce that yesterday's photo was indeed taken in reverse. While the reason Duncan gave was correct, it's not the reason I was probing for - read on.

South Africa has a few large roads that carry traffic in one direction only. If the line on the road (in yesterday's photo) were white then this road would be one of these roads (carrying traffic in one direction only) and I would have been taking the photos facing forwards.

If you're ever driving in South Africa and find that darkness or fog prevents you from seeing too much, take note of the solid lines on the left and right of your vehicle - left should be yellow, right should be white... if that's not the case, pull off the road really fast!

Surprisingly, this does happen - I once experienced two such incidents in a single day. Leave a message if you're interested in reading the story and I'll add it as a comment.
