Power was the new big thing at the time. The Chickamauga Dam (middle of Chattanooga) was almost finished an TVA wanted everyone coming in to the city to fall in love with electric power. TVA was not though highly of at the time outside the city an needed to change peoples minds. Did not really work. The people in the City had all these new jobs but the communities around the city just saw the government coming in an taking away good farmland by force. Where I am anyway it was the 1960s before people started adopting TVA power in mass. Right about the time TVA got done flooding people out of their homes. In door plumbing would take about 20 more years though.
