Not an easy puzzle as most objects are washed out. But this is what can happen with fog. Objects can become extremely difficult to see. Be extra careful when walking in fog as drivers can have greatly reduced visibility. Before you cross the road, Stop, Look, and LISTEN. You can often hear a car coming before you will see it (and the driver sees you).
