The heat can be a problem in the summer, but if I offset to go earlier in the morning and return earlier in the day, I can ensure I'll be sweaty at home in the evening, rather than at work at the start of the day.
Re: Ask HN: What is your commute like?
#21Tempe, AZ - Office is just under 2 miles from my house. I usually bike, which takes ~10 (leisurely) minutes.
