Perfect fall rides, although most of the leaves are now on the roadway. I had a scary illustration of what is wrong with relying on reflectors. 2 pedestrians were walking against the traffic (as they should) on a dark stretch. One was wearing a reflective vest over otherwise dark clothing. I did not see them until we were close to colliding. Apparently my light beam's angle to illuminate the road surface for me doesn't get enough height to give good reflection off the vests, and it is a relatively narrow beam. Reflectors are good at sending light back to the light source, which in this case did neither me or the peds any good. Active lights are essential.
