Simplicity is best

I was watching a road work crew (no, this isn't a hobby, I was a a red light) and was impressed that they had one vehicle digging a trench, a crew laying pipe in the trench, and another machine burying the pipe, all in a line about 100 yards long. It seemed amazingly efficient to me. It reminded me of when I drove cross-country with friends and I marveled as we drove through Iowa at how straight and even the rows of corn were. My friend, who had grown up on a farm, replied, "Easiest way to plant them."
