Carnegie isn't the ghost town on the postcards, which is exactly why it's worth knowing about.

It was established in 2002 at the NASA Ames Research Center in Moffett Field.

San Joaquin County holds 4 documented ghost towns, including Elliott, Liberty, San Joaquin City — Carnegie keeps them company on the map.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.
