On my morning route I often see walkers, runners and other exercisers by the side of the road. Trends in gear can shift by season or by fashion. It seems day-glo colored running shoes are popular now. That makes sense for visibility and safety. For that reason runners wear reflective garments also. But! None of that arrests my attention as a driver as much as the rather podgy middle aged man running along in black bicycle capris, gloves, sneakers and nothing else as he carries his briefcase to work. When I see him I check the temperature on my dashboard. Today it was 41 degrees.
