First bike commute since January 29 due to snow, sleet and rain over the past week or so. There has been a lot of black ice on the roads here every morning, so I didn't feel safe commuting again until today. Rode yesterday with a friend and we still saw a fair amount of black ice even at 11 am, but lots of afternoon sunshine and warmer temps finally cleared most of it off. There was still one spot on my commute where the entire right lane was covered with ice, but I was anticipating it, and switched over to other lane.
