Is there a women only service in San Diego?
The Guru Take
See Jane Go has closed. Women Driving Women may be a new option.
There used to be See Jane Go in Southern California (primarily in Orange County - near LA), but they have sinced closed doors.
There seems to be a new company called Women Driving Women (http://womendrivingwomen.org/). I am not personally familiar with them, but let me see if I can find out more.
