Our neighbor, who owned a large electrical contracting company in Pittsburg, added lightning rods as the very first addition to his home. He used copper wiring and grounded it deep.
In fact we met them while both homes were being built and he told us how the lightning rod system would be installed. It was their third home in The Villages.
Everytime I see this photo of the Hancock building in Chicago, I tell myself that we need to get Lighning rods installed.
