A while back I found a little mirror on the shoulder of the Sammamish Parkway. The stick-on helmet mount had obviously not been up to the job so I got to thinking about a way to put my road find to use. I clipped off the faulty mount and replaced it with an office binder clip and a couple of rubber bands.
I always wear a cap under my helmet so I clip the mirror to my cap brim whenever I go for a ride. BTW, the cap in this picture is an REI runner's cap and the trim is very reflective. You can see the cap reflecting the flash from Tarik's camera here.
And yeah, I know it looks dorky. I made my peace with being a dork a long time ago.
