The saga as old as the invention of the bike, great post. SO I always struggle with being the bike "police" I don't yell at bike riders when I am driving but when I too am riding I always find myself debating if I should say something, especially to riders going against traffic, then don't get me started on parents riding with children going the wrong way in traffic. But if I truly say I am a biking advocate than I should be letting people know they are breaking the law and gambling not only with their life but mine as well. Maybe the university cycling club could start handing out reflective sticky tape as riders come onto campus on these dark fall mornings
