The Annual Sturgis Rally is the largest celebration of the motorcycle in the world. Every August, hundreds and thousands of visitors descend on the tiny town of Sturgis, South Dakota for full throttle action and adventure. Host Don Wildman visits the Sturgis Motorcycle Museum where he learns about the story of two spirited sisters who broke boundaries while attempting the unthinkable. He heads to the frontier town of Deadwood to uncover one of the most perplexing crimes in the history of the Black Hills. And, in nearby Wyoming, he delves into the tale of one reckless daredevil who attempted a dangerous and groundbreaking feat.
