During the Great Depression, millions of Americans rode the rails searching for work, food, and survival. But these wandering hobos weren't just drifting aimlessly. They were part of a vast underground network that communicated through a secret language of symbols chalked on fences, carved into trees, and scratched onto buildings. A cat meant a kind lady lived there. Two interlocked circles warned of handcuffs and police. A triangle with hands told you to expect a free meal if you told a hard luck story.

The Hobo Code was a survival guide written in simple marks that could mean the difference between a warm meal and a night in jail, between a safe place to sleep and a vicious dog attack. This wasn't just graffiti. It was a sophisticated communication system passed between strangers, a way for America's most desperate to help each other survive.

Join us as we decode the mysterious symbols of the hobo subculture, explore the unwritten rules of riding the rails, and discover how this secret language helped thousands navigate the hardest years in American history. From hobo jungles to the last practicing hobos still riding today, this is the hidden history written on America's back fences and railroad tracks.
