Recently my husband and I had to begin carpooling. Our youngest son achieved one of his life’s goals…he got a driver’s license. That meant he could drive to school rather than horror of horrors take the bus. It also meant that because he was now 16 he could enroll in work-study and get out of school early. While he thinks he’s really hot stuff he hasn’t given much if any thought to the impact of being a driver without free access to a vehicle. So that’s how my husband and I have come to carpooling. Today as we were driving in, and passed the light rail station, then we had to stop for a train, and as it passed I could see that someone had their bicycle with them. I turned to my husband and asked, “Do people often have their bikes with them?” See, even though I drive him to work he does take the train home in the evening because we can’t mesh our afternoon schedules as easily as we do our mornings. He said, “Yes, they get off the train and then bike to their final destination.” Ok…so bikes on the train got me to thinking about…
