California Association of Realtors
No it's not an automobile event, nor the California Association of Republicans event. It's the California Association of Realtors annual event taking place in San Diego, October 10-12.
Realtors from throughout the state will gather to network and go through technology and training. Some realtors come from out of state.
The expo usually rotates between San Francisco, and San Diego. I don't recall it being in Sacramento.
Anyway, if you can't find your realtor it's probably because he/she is in San Diego doing some business and having some down time. What do they call it? Yeah, a vacay!
