When Krisi Riccardi was a girl, her father used to take her on leisurely Sunday drives down Highway 1. She'd enjoy the beautiful scenery until they hit Pacifica, where something odd always caught young Krisi’s attention — a stone castle perched high on the hill. Not exactly what you'd expect to find in a laid-back beach town. “As I got older we would walk up to this castle and walk around it. I’ve never been inside, but I looked over the wall. I’m now 68 and I always wondered what the history was of this castle,” Krisi said. She isn’t the only one curious about this place. Her question won a Bay Curious voting round. Today, Katrina Schwartz takes us inside the castle to explore why it was built, and the many lives this place has lived. Additional Reading:   Rum Running, Ghosts and Speakeasies: The Many Lives of Pacifica’s Castle Sam Mazza Foundation website Reported by Katrina Schwartz.

Terese O'Malley commuted across the Richmond-San Rafael bridge for years, and always wondered about a landmark visible from the bridge: San Quentin State Prison. The maximum-security prison sits on a primo piece of waterfront property in Marin County that would likely sell for an unfathomable sum in today's market. "How did Marin end up with San Quentin prison?" she asked Bay Curious. And why hasn't it moved?Editor's Note: We finished production on this week’s story about San Quentin prison in February 2020, just before Coronavirus took hold. In the months that followed, a few cases at the prison grew to more than 2,200. Ultimately two-thirds of people at San Quentin got infected, and 29 people died. It was one of the deadliest outbreaks in the nation’s prison system. Things have mostly turned the corner now that the majority inside are vaccinated, but questions remain about how things were handled. Long term effects from the outbreak are still being felt. In addition to our episode, we encourage you to listen to The Bay's episode from April about life at San Quentin today.Additional Resources: The Lasting Impact of COVID-19 in San Quentin State Prison (The Bay podcast episode) Court Hearing Examines Whether San Quentin’s Deadly COVID-19 Outbreak Could Have Been Prevented Reported by Kelly O'Mara. Bay Curious is made by Olivia Allen-Price, Katrina Schwartz, Sebastian Miño-Bucheli and Brendan Willard.

A lot of listeners, including Steve Held, want to know why Bay Area cities aren't investing more in desalination plants as a long term fix to our water problems. We’re a state with 840 miles of coastline. Most of our big population areas are near the ocean. Why don’t we have more desalination plants? In this episode, we'll also talk about wastewater recycling and water budgeting.Additional Reading: What Can Local Water Agencies Do to Boost Water Supply?

For most of us in the Bay Area, the journey our water takes to reach us is hidden from view. It travels long distances, sometimes more than a hundred miles! That can leave us disconnected from the source. We go about our days oblivious to how precarious our water resources might be. Today we’re going to answer what seems like a really simple question: where does our water come from? Because where your city gets its water has a lot to do with how you’re experiencing the drought right now. Additional Reading Bay Area: Do You Know Where Your Water Comes From?
