Ghost towns in the bay area:
Drawbridge, California (Near Alviso) and
Holy City, California (on HW 17)
Alviso north of 237 is a old Mexican town. Many homes & establishments are old and having Mexican flavor all over. There is a train track and the trains go on them ones a day or so (actively used).
The southern part of Alviso is modern and have newer companies like other areas in the south bay. Guadalupe River and Coyote Creek flood here... Last big flood was in 1983. The levee has been strengthened since.

Alviso is currently part of SJ (not too sure).
An electric generator came to the town during the fall of Gov Davis - California energy crisis.
