Your support ensures that this unusual, human-powered, pedal-pushed, kinetic art sculpture vehicle event continues to bring joy, creativity, and community to Corvallis. From mud pits, sand dune climbs to water and land crossings, every glorious, gear-filled moment helps spark imaginations and showcase incredible talent—all thanks to you.
