 High above Cal State LA is an unobstructed bird's eye view of the sprawling campus. And it just happens to be the best spot to plant a radio transmitter. Caltrans dispatched Matt Johns and Tom Hartley to set up this highway advisory radio system or HARS. Its job is to broadcast a pre-recorded message in both English and Spanish to everyone driving up to get their COVID-19 vaccination. The message tells them what to expect and gives them instructions to help speed up the process. Y'all hooked up? Less than 30 minutes later, it's live. Welcome to your community COVID-19 vaccination site. In Los Angeles, I'm Shawn Boyd, OES News.
