Resurrected: Spooked at the Smithsonian
The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the Smithsonian home to countless tales of unexplained phenomena and—dare we say—ghost sightings?

Pamela Henson, Institutional Historian at the Smithsonian Libraries and Archives

CSI: Southern Pacific
Looks like these criminals used correct postage, 'cause justice is about to be delivered. Okay, there are no snappy one-liners in this crime scene investigation, but there are explosions, collisions, manhunts and even a cow who was in the wrong place at the wrong time. On the centennial of "The Last Great Train Robbery," we re-examine the evidence to find out how U.S. Postal Inspectors tracked down a band of old school outlaws using cutting edge criminal forensics...and postmarked them for prison.
Guests:
Lynn Heidelbaugh, curator at the Smithsonian National Postal Museum
Chelsea Rose, Director of the Southern Oregon University Laboratory of Anthropology
Kate Winkler Dawson, author of American Sherlock: Murder, Forensics and the Birth of American CSI

The 'Gentle Anarchy' of the Muppets
Icky Gunk. Moldy Hay. Kermit. You might recognize one of these names. Before Kermit joined Miss Piggy and Big Bird, he was kicking it with Sam and Friends — a local tv show in Washington, D.C. that launched Jim Henson's career. We journey back to 1955 to figure out how this eccentric cast of puppets built the foundation for everything Jim Henson would do afterwards, from Sesame Street, to The Muppet Show and even Labyrinth (we see you, David Bowie fans). And we venture into the conservation labs to learn what it took to revive these crumbling hunks of foam and fabric when they landed at the Smithsonian.
Guests:
Ryan Lintelman, curator at the Smithsonian National Museum of American History
Sunae Park Evans, senior costume conservator at the Smithsonian National Museum of American History
Bonnie Erickson, a director of The Jim Henson Legacy; creator of Miss Piggy
Craig Shemin, author of Sam and Friends: The Story of Jim Henson's First Television Show

A Wild Ride on the Pony Express
In 1860 the fastest way to get a message to a family member, partner, or colleague wasn’t by text but by hoof…specifically, a pony’s. In just ten short days the Pony Express delivered mail between St. Louis and Sacramento. To find out what it was like to travel this legendary trail, there’s only one way: get on a horse and follow all 2,000 miles of it. That’s what writer Will Grant did, retracing the route from Missouri to California over four and half months. This guest episode of the Outside podcast brings you an epic camping tale in the name of history.
We’ll be back with new episodes of Sidedoor in September! If you enjoyed this episode, find more stories from Outside at https://www.outsideonline.com/podcast
