About twenty-five years ago, a young and innocent Mennonite farm boy from my home town bought his first car, a shiny new Triumph TR4. Together with another young Mennonite friend, they put the top down, and headed off for a trip to Mexico. It was the first time either one of them had travelled out of the country, other than a short drive to the US.
Travelling a sunny mountain road in Mexico, they stopped to remove a small tree that had appaently fallen across the road. But it hadn't fallen, it had been put there. The bandits took every penny the boys had. Young Stewart, the car owner, began to cry, not knowing how he would get home to peaceful Chilliwack with its green mountains, plowing competitions, and mom. The bandits were so moved, they gave him some money back. That's a true story.
And here's one a bit like it...
