Today’s walk was dominated by fog. As the day passed, the fog grew thicker, and by the time I went for a walk, I could barely see beyond 200 feet.
Fog is vapor cooled to the point at which it becomes water. Water is the only substance that can change from a gas to a solid or a liquid, all determined by the temperature. This is why fog looks like a floating sea, suspended above the snow.
Better to be walking in that than trying to drive blindly in it!
Great point, Paula. Night driving is especially bad. Same as under water, light either illuminates or blinds, depending on its direction. A car’s headlights hit the water droplets in the fog and the light gets reflected back to the driver, making it impossible to see. Be careful out there!
