You worked as a driver in a steel mill, and every time your work day starts so that your huge truck with a trailer is loaded above the norm, and you go on your route to unload the goods. In general, it does not seem to work hard if your route does not pass through the marshland. Go forward, slowing down on the length of the path, which has the largest number of different obstacles. Make sure that the goods have not fallen out of your body and you deliver the goods intact.
