I jinxed myself. On the way home, I noticed that I had hit EVERY light green. When I got to bike path, it was packed with bumpy ice, but I was making very good time. It was a fun commute. When I got home from the seven mile commute, I started to load my bike on the repair stand with the saddlebag still on when I remembered that started the trip home with TWO saddlebags.
It was after dark, but I re-traced my steps. The saddlebag was off to the side of the path 3-4 miles toward work. Fortunately, the path is not well-traveled this time of year.
