Ever raced cyclocross, mountain, or road bikes at Portland International Raceway? Ever biked on the Columbia River Slough northwest of Kenton? Or maybe you’ve enjoyed the annual Winter Wonderland Light Show? If you answered yes to any of those, you’ve ridden on the streets, across the yards, and around the borders of Vanport.
