Once upon a time, dirt roads were the only roads. In Wyoming there are more dirt roads than almost anywhere else, so Ari and Zack decided to step back in time. They found two vintage dual-sports, a 1975 Honda XL350 and a 1969 Yamaha DT-1, and tried to ride all the way from the eastern border Nebraska to the western border with Utah, without their tires touching pavement. The boys faced snow, wind, and mud for days, and at the end they came home with another epic Common Tread XP adventure.
