-21 when I left for work yesterday. Had I had my act together and left 30 minutes earlier like I was supposed to, I could have rode at -23 which would have been a personal low temp for me. Ah well.
I am somewhat surprised at the big deal being made out of this cold snap, - at least locally. It's been this cold here many times before and it will get this cold again. Seemed like it happened fairly regularly when I was in high school but lately triple digit temps are more common than the -20s. I think it's been 4 or 5 years.
