This week on Stagger:

J.D. and Derrick talk about the genesis of one of the most legendary families in motorsports - the Unser family. And specifically, the guys wanted to explore the link between the Unser family and Pike's Peak. The annual hill climb race has been dotted with Unser winners throughout it's existence. But you may find it surprising just how much Bobby, Big Al, and Little Al owe to that hill climb event. 

Later, we hear from Don Sanborn, the president of the Pike's Peak Hill Climb Historical Association about what it means to be a family with ties to that mountain, the earliest days of the hill climb, and what it means to his family to be a part of keeping this race going.
