When you're on a self-drive safari in any national park in Southern Africa, you MUST be back in the camp by sunset, or you will have to pay a sizeable fine. At the same time, the light just before sunset is the best for photography and wildlife watching in general.

So, just before sunset, this is what we see on the roads leading back to the camp; people driving like mad through the dust from previous vehicles to be in camp before curfew.
