Two iconic figures intersect this week as Harley-Davidson riders led by motorcycle scion Bill Davidson take the road to discovery on Route 66. "The American Road Tour" was created by Davidson, vice president of the Harley-Davidson Museum and great-grandson of the company founder, and his team. Davidson said when he surveyed the mass of historic items from the new "American Road" exhibit (opening at the Museum this week) he realized that there was no actual "tour."
