Normally I ride home in daylight. I had to work 1/2 hour late and thot OK only a 20 minute wait for the bus. Wrong the Transit system has added a new transit mall to improve service and most busses are running 20-40 minutes late. The sun had set at the bus stop and I was putting my morning commute cloths back on before the bus got there. Glad I had my new 100 watt headlight with me.
