## Resource

From gold rush boomtowns to transcontinental railroads, the U.S. Postal Service played a pivotal role in connecting a rapidly expanding nation. In this episode of Mailin' It, hosts Karla Kirby and Jeff Marino welcome USPS Historian Steve Kochersperger to explore the remarkable stories behind mail delivery during America's westward expansion. Discover how postal employees once disguised themselves as passengers to outsmart railroad companies, how the California Gold Rush transformed mail delivery and helped launch companies like Wells Fargo and American Express, and why the Pony Express became one of history's most misunderstood mail services. The conversation also uncovers the dramatic story of the "Silk Train," the infamous Tunnel 13 mail robbery, and how those events helped shape modern federal forensic investigations and mail security. Along the way, the hosts also share a fascinating look at the unique Texarkana Post Office, where one building serves two states at once.
