I thought it might be a good idea to have a mirror for my road rides, so I bought the kind that hook onto your glasses. I've only tried it twice, and maybe didn't give it enough time. I kept having to move my head around to different angles to see what I wanted to see behind me. I never felt secure enough in that tiny reflection that I could rely on it to make any moves. So, I put it aside and continue to rely on my ears and a glance over the shoulder.

I will be interested to hear others' reports of their experiences with mirrors. Maybe I chose the wrong kind, or didn't give it enough time.
