Biking to work is always the best part of my work day. Daylight and cold, windy, snowy Iowa winter's pretty much puts an end to my commute mid October- April. Roughly corresponding to commuting only with Daylight Savings Time.

Having kids also curtails many if my daily commutes, their activities are a handful. Got one kid driving now which helps some.

So during mostly the summer I usually commute 3x a week.
