My commute was
rough. Literally. Packed snow that had partially thawed yesterday, and re-froze over night. I got lucky for a little while because someone (an electric company truck I think) with a dual rear axle truck had driven on the trail so I had 4 relatively smooth (but narrow) tracks to pick from.
They didn't last the length of my ride though. I averaged around 6MPH. Slow going. I need a full suspension bike.
20F degrees.
