As I was taking the girls to preschool this morning, we passed by a woman riding a bicycle while talking on a cellphone. Not with one of those fancy hands-free devices, either - she had one hand on the phone, which in turn was up to her ear, and one hand on her handlebars. I'm amazed that between the traffic noise and her bike helmet, she was able to hear anything. And it got me to wondering when I'd see the first "Hang up and pedal!" bumper sticker. You know that as fewer people drive and more people bike, it's gonna happen sooner or later.
