Saw that article too. I've had two young women in the office approach me this year about riding through the winter. My sincere hope is that it isn't some sort of fad but a long term trend.
As encouraging as it all is, it seems to be a largely urban phenomenon. About a year ago in a casual a conversation at a Christmas party, somebody asked what I drove to work. I told them that I usually rode my bike. There was a strange silence while several people looked at me as though I was from another planet. Then the topic of the conversation changed. This took place in a distant suburb at my wife's uncle's place. That family loves their motorized machines so I suppose I shouldn't have been surprised. I guess I'd been lulled into thinking that biking to work isn't that unusual.
