More than 154 million treasures fill the Smithsonian’s vaults. But where the public’s view ends, Sidedoor begins. With the help of biologists, artists, historians, archaeologists, zookeepers and astrophysicists, host Lizzie Peabody sneaks listeners through the Smithsonian’s side door, telling stories that can’t be heard anywhere else.
