Today, San Diego’s transportation system is highly developed and incredibly convenient, whether you prefer driving or choosing public transportation like buses, trolleys, or the Light Rail. But going back one century ago, personal automobiles were rare, and most people relied on the services of various auto stages to travel. This early bus in the picture was owned by the local auto stage in La Mesa, connected to the streetcar from San Diego. Each ride carried 15 passengers and ran five trips per day.
