My great grandfather was a tunnel builder. His specialty was working in soft or wet ground like under a river or lake bed. They lived in Chicago for several years, he built a couple of water inlet tunnels under Lake Michigan. Near the bottom of this image, is one of the inlets for one of the water tunnels he built. Tangible evidence of his life’s work. I love the work I have done, but 100 years from now no one will fly over and say, David did that. At times I wonder if I should have become a brick layer or stone mason.
