To some, the Freight Train Riders of America is a vast, secretive criminal network -- deadly ghosts, haunting the country's rails. To others, the FTRA is a loose collection of outcasts doing their best to help each other survive. To still others, the FTRA is nothing more than an urban legend, and never existed at all. In tonight's episode, Ben and Matt dive deep into the hidden world of trainhopping culture, searching for answers to these conspiratorial tales. Be advised this episode may not be appropriate for all audiences.
