Abandoned Memories is short on text but thick with photos. Even without captions for every picture, contextual clues can give us a disturbing idea of what life might have been like in the Wayne County Child Development Center (before it was abandoned, razed, and turned into a golf course). The rather-less-easy-to-navigate Northville-Tunnels.com also has photos and information.
