I learned that when I need to commute by bike in the winter that I need to get up earlier. I was running late on more than one occasion back in February, luckily my boss understands my situation and gives me a little of a break as long as I make up the time after hours. I learned how important BRIGHT lights are on back roads in the dark. I managed to brave the freezing temps back in February, but whenever there was precipitation mixed in I would turn back and carpool for my own safety. Next year I'll probably finally put fenders and wider tires on my bike to be able to ride in the inclement weather.
