I regret why i din't start commuting early in 2014. Total miles for 2014 was 6,300 with about 3k from commuting. I din't like sharing road with cars so i would drive 6 miles and commute 15 but i discovered a different safe route and now it's a total of 21 miles one way!
Today's commute was 30 deg cold but this year i'll commute 4 days a week for a total of 160/week unless thunderstorms.
