This was the indispensable part of the puzzle: the truck. Sherriff drove this truck from the waste dump to first working place, then from the first working place to the second working place, then from the second working place to the factory: the end of the line. Every time it was loaded, I thought: now it is really full. But then another bag was pushed up and tied to the truck. Driving it was the most dangerous part. At every turn the balance of the truck was challenged, waiting for the moment for the truck to fall over.
