Wild and whimsical machines gathered in Corvallis for the 30th annual Graand Kinetic Challenge, a two-day human-powered sculpture race over land, sand, mud and water. Teams dressed in colorful costumes pedaled their homebuilt machines along city streets, bike paths and a man-made sand dune on Saturday. Then on Sunday, they slogged through a 150-foot mud bog and float 1.6 miles of the Willamette River, before racing back to the finish at the Benton County Fairgrounds. The Graand Kinetic Challenge
