I've worked it out in the past... we have about 225 days a year at my job (9/80 schedule, holiday shutdown and a few holidays) and I was accruing 3 weeks vacation and 2 weeks sick for a total of at least 202 working days a year. My commute is just over 11 miles round trip. If I commuted every single day, the total would be in excess of 2200 and likely more than 2300. So it pains me a bit to look at my sub-500 mileage number. All that lost time in cars... at least I'm riding home tonight! ciao
