I don't see a way to do 500 miles per month during the Boston winter. Especially THIS unreal, unbelievable festival of snow, sleet, and other precipitive crap. it's piled so high and wide that I can barely get one car down my street. and the city has given up plowing the MUPs. So commuting has become a real slog and almost not worth it.
But, assuming I do the usual 26.2-mile round trip tomorrow, I'll just barely hit 300 for the month.
