I'm glad I drove my wife in to work today for her 6am shift as it gave me the opportunity to see the conditions and read the car's readout of air temp, 4C. The roads were wet from overnight rain with some puddles but no active rain. After returning home from dropping off my wife, I started out on my bike and before the end of the road, decided that I wasn't dressed well enough on top so I returned and got a shell that turned out to be just what I needed.
I was tired when I started: I picked up my son from his work, returning home at about midnight, set the alarm for 4:30am to wake up my wife and settled in for a 4.5hr sleep. I dozed while she got ready but the dog didn't get it, he wanted to play so I didn't really get any more sleep.
What I needed for today's commute was a recumbent with a pillow and blanket, oh, and an electric motor.
