The Flat Landscape of Kansas On the whole, Kansas has never really been thought of as a driving challenge. A glance at a state road map reveals a grid-like layout with relatively few twists and turns. Doctoral student Brandon Vogt knew that from personal experience. He frequently drove the width of the state, making the trip from Boulder, Colo., to Colombia, Mo. And he began to wonder just how flat Kansas really was. Vogt's research now confirms his suspicions: Kansas really is flatter than a pancake. Robert Siegel talks with Vogt about his findings, which are published in the Annals of Improbable Research.
