More people are getting out and riding their bikes and walking - on streets, on paths, everywhere. We need to do better at sharing these common spaces, co-existing safely. Some are strong believers in using some sort of signal, whether verbal (such as "on your left") or other sound. Others want everyone to slow down. Being more aware of one's surroundings would seem to be a good start. What's your $0.02 on this? Please leave comments.
