In the relatively sleepy town of Chattanooga, in Tennessee, you’ll find an old AT&T building. For a many years, the building sat unused and abandoned. It had a lot in common with its hometown; a place that was once vibrant and alive, but had since fallen on hard times. This is not an unusual story, particularly for smaller American towns. While the big cities are so bustling and busy that they barely find the time for sleep, some neighborhoods have been living a permanent twilight zone of deterioration and neglect.
