Meet two “pedal pushers” with a cause. Amy and Dave Freeman are adventurers and authors who are part of the National Geographic team trying to raise awareness about keeping our Boundary Waters clean. They were traveling through Indianapolis recently on their over 2,000-mile trip – on BIKES – and our cycle enthusiast, Steve Sweitzer, caught up with them. Keeping our waterways clear and clean is their mission. You'll love this scenic story with an urgent message.
