L39-1: Nothing to worry about
The rough across the plain soon became so bad that we tried to get Bruce to drive back to the village we had come from.
Even though the road was littered with boulders and pitted with holes,
Bruce was not in the least perturbed.
Glancing at his map,
he informed us that the next village was a mere twenty miles away.
It was not that Bruce always underestimated difficulties.
He simply had no sense of danger at all.
No matter what the conditions were,
he believed that a car should be driven as fast as it could possibly go.
As we bumped over eh dusty track,
we swerved to avoid large boulders.
The wheels scooped up stones which hammered ominously under the car.
We felt sure that sooner or later a stone would rip a hole in our petrol tank or damage the engine.
Because of this,
we kept looking back,
wondering if we were leaving a trail of oil and petrol behind us.
