San Francisco was built around a huge fleet of ships that brought people and suppies during the Gold Rush 150 years ago. Some of them are still buried under the the city. Todd talks to archeologist Allen Pastron who unearthed one of these historic ships: underneath his favourite Chinese restaurant. Allen Pastron is an archeologist for Archeo-Tec.

A mysterious flash on the Moon caught on camera 50 years ago is still provoking disagreements about its origin. Bonnie Buratti an Astronomer at NASA's Jet Propulsion Lab, joins Todd to talk about what she believes caused the flash; a 20 meter asteroid hitting the moon.

Todd is joined by author Elizabeth Freeman to discuss her book, "The Wedding Complex: Forms of Belonging in Modern American Culture." They talk about Freeman's idea that the wedding is often a combination of public forms of attachment, ceremony and pageantry rather than a sense of community.
