The Kinetic Kops do krowd kontrol for the Kinetic Sculpture Race. Mostly to keep spectators, especially spectators with cameras, from being run over. Some of these machines are large and heavy and may not stop on a dime. Some of them went down to the water fast, gathering momentum, with spectators lining the way. People get distracted by the costumes and glitter and forget that these are built to climb hills, go through mud, go on water, human powered.
So Kudos to Kinetic Kops for protecting us all!
