Today, the city of Oakland is holding a celebration rally for one of its homegrown stars ... Olympic figure skater Alysa Liu. She's the first American woman to win gold in her sport in nearly a quarter of a century. Liu grew up in Richmond ... and trained in Oakland throughout her career. Her coach Phillip DiGuglielmo is also based in the Bay Area ... and was part of her team for the Milan Winter Games. I spoke with him and he started by telling me about the moment when Liu decided to return to skating after her two-year retirement.
