After my first Cycle Toronto board committee meeting, I found a red cycling tail light on the sidewalk. I set it down in a small pool of light, but someone else picked it up for a look. As I was unlocking my bike, another cyclist was frantically trying to find something. I asked her if she'd lost a light, and she had.
So I told her where to find it, and took her to the spot. And it was gone. She was stranded in the dark, with no tail light. On Bathurst, which is paved with a patch lifted from the surface of Mercury, and devoid of cycle lanes. So I did the only thing I could do, I left her. With my MEC tail light, cruising only with my smaller, ancient, dimmer AAA-powered OGC.
