Second day commuting this week. I had to drive to a service call yesterday. Days like those require me to carry my laptop and a couple of hand tools, as well as project folders, etc.
When I got to work this morning, I weighed my case. It seemed quite heavy, and it was. 22 lbs of additional weight in today. Luckily I don't have to carry it all home tonight.
This was my first commute in upper 50F temps. It was cool when I first started, but it was nice not to be really sweaty when I got to work. We won't see snow here for quite some time.
