I was a year-round bike commuter for about 5 years - 8 to 10 miles one way. Always enjoyed the start and end of the day with a bike, even when the conditions were terrible. Being in Minneapolis, it took a few years of 3 season riding to build out my kit to handle the worst of winters weather (dark, snow, ice, sub-zero temps).
Now I work from a home office, I get out to ride nearly every day, but now I have more options to ride when the weather is nicer and the traffic is lighter and/or routes with light traffic. I miss the daily commute, but enjoy the current situation too.
