Since I am new to the Bay Area, a concern over safety is always in the front of my mind. I am curious about the areas to stay away from.

Thank you for any advice and help concerning this.

San Francisco, Tenderloin.

Are you asking about areas that are safe to work, either incall or outcall?  

or just areas that you should avoid if you were a civilian? ie don't go to these places late at night.

The reason I ask is because some places that are "safe" for civilian non escorts, aren't necessarily safe for escorts due to LE activity.  Some of the PD in the suburbs where crime rates are lower than the cities need to justify their shiny toys and budget so they are a little more vigilant about this than in SF.

I would have to say Oakland, Vallejo
