I need some help. I love biking in to work, and the cold really doesn't bother me. I live in Pittsburgh and work out in the suburbs. I never have a problem biking in the city, with street lights and the amount of bikes around I always feel safe. The suburbs, however are another story. I have never biked outside the city when it is dark out, and was wondering how safe it is. With narrow roads and little shoulders, is there a good way to bike in the dark out on the back roads? I don't want winter to stop me from biking in with my new job. Any help/advice is appreciated!
