Fog

It was particularly foggy this morning. So foggy that I couldn't see more than 10m in front of me on the drive to school and so didn't see a car coming towards me as they hadn't turned on their lights.
Nothing happened though, fortunately.

I took this photo on the walk from the place where we park our cars to school. Usually you can see right down to the end of the path (about 150m or so).
