See and be seen
Daylight savings time is an odd beast. I’ve heard several explanations on its origins – ranging from bankers and stock brokers, to farmers wanting their children to be able to get chores in during daylight hours before school, to railroad interests. Clearly they didn’t consult with bicycle commuters on their opinions, though, as the time shift puts the normal commute home into complete darkness.
It is a very subjective opinion, but city traffic in the mornings seems to be less hectic than traffic on the evening commute. Perhaps it is because folks are anxious to get home – or to the pub – quickly after work, but not quite so rushed to get to the office in the morning. Whatever the cause, I much prefer to ride in morning darkness compared to evening darkness.
