You can tell you are in Oakland by the color and design of the street signs. This is a handy way to know when you are leaving the wonderful confines of home.
Nearly all Oakland street signs are green with an oak on them. Older signs don't have the oak tree, but all of them (with a few minor exceptions) are Mixed Case (as opposed to Piedmont's ALL CAPS signs). There are a few special locations that have blue and white and no oak tree. In Oakland's Chinatown, the standard signs are supplemented by smaller signs in Chinese (Q: is this Mandarin or Cantonese or ?)

Neighboring towns/cities have different street signs and colors.
Berkeley street signs are brown, unless they are designated bicycle boulevards, in which case they are purple
Emeryville street signs are blue, unless they are designated bicycle boulevards, in which case they are purple.
Piedmont street signs are green, with no oak tree, and in ALL CAPS.
San Leandro street signs are green with cherries (or some other cute little dangling fruit) on them.
Our Oakland has a fabulous comparison of these signs, including pictures.
