On this week's Sweep the Floor, we meet Washington State-based artist/fabricator/car enthusiast David Harto, who races at Bonneville on a bike powered by a 1952 Cushman Eagle scooter motor. He walks us through the minutiae of salt flat racing; describes the neverending evolution of his very artistic creation; and explains how a guy who doesn't even consider himself a motorcyclist ended up racing on two wheels, trying to break the ton (a.k.a. go 100 mph).
