#150:A Journey In The Desert
One day, nine travellers, each with their own car, meet on the northern edge of a great desert, their goal is to explore the interior of the desert by constantly driving due south. Each car can travel forty miles to the gallon, which is also the capacity of their cars' petrol tanks. Their tanks are all full at the start of the journey, and each traveller can also fit nine extra gallon tins of petrol in the back of their car. During the journey, extra gallon tins of petrol can be moved from car to car. None of the travellers can leave their car and they can't leave any caches of petrol along the way in the desert since they might get stolen.
HOW FAR SOUTH CAN AT LEAST ONE OF THE TRAVELLERS REACH, GIVEN THAT THEY ALL NEED TO RETURN BACK NORTH TO THE EDGE OF THE DESERT?

The River Mazy Part 2
Being relatively shallow, it is not difficult to build tunnels underneath the River Mazy. As a result, there are numerous tunnels connecting subway and road services north and south of the river, and evidence from records and microgravity studies indicates the exisence of several older tunnels.
