Back to normal Spring weather today: overcast all day with a few sun breaks, no wind & the clouds meant it was not as cold as previous mornings. I rode a ways with another commuter at 6:15 AM. He had a neat blinkie mounted on his helmet, the lights blinked around in a circle sequentially. Haven't ever seen one like this before. I only saw it when he turned off my route & rode away so I couldn't ask him the brand or where he got it.
Maybe next time. Don
