20F and a nice ride home - and I was surprised to see 4 other bicyclists out (which is more like what I see in summertime).

One was a very rare sight indeed... a salmon with a rear blinky light. That one dominated my thoughts for several blocks afterward. Why on earth would you put a red blinking light on the back of your bike... and then pedal on the left side of the road, against traffic? Who is going to see the light? Why??

Perplexing.

A great commute, though.
