Anyone who's been to Botswana will know about the veterinary control gates on all roads, which sometimes double as police points. My son was briefed to always stay between two adults, and not to take his helmet or goggles off at any of these stops.
From Mokubilo we had to do around 30km of tar before turning onto the dirt again. As luck would have it, there is a control point with police and all, right before the turn-off. I was at the front, and before the officer could say anything, I started asking for directions, and when he pointed the to dirt road, I promptly pulled off, with the other two in tow. Or so I wished. I only looked back a few hundred meters before looking back, but when I did, I was horrified to see my son's bike on its side right in front of the control gate, with the police officer next to him.
