I just got off the phone with my father-in-law. He is a long-distance truck driver. He also is a former blacksmith, U.S. Army Green Beret and general tinkerer. What he is not: computer savvy.
I come from a manufacturing family. My dad works as a technician, servicing presses at a major commercial printer. My aunts and uncles all work for the same print company. My brothers are engineers for major heavy-industry and aerospace manufacturers. And then there's me.
