River County, Disney's first water park has been shut down since 2001 and permanently closed since 2005. It has not been dismantled.

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.
