In 1910, Floyd Clymer, then age 14, and his younger brother, Bill (age 11), attempted to drive from Denver to Spokane by themselves in a Flanders 20. They followed rough, rocky roads through the open prairies and high desert, sleeping out in the open beside clumps of sagebrush. Now much of their route (between Laramie and Walcott, WY) can be driven on I-80. When they broke down west of Laramie, they found the railroad tracks heading west and walked to the nearest flagging station where they sent a telegram home asking for spare parts.
The youngest of the five us are also ages 14 and 11.
