In this video, Whit Overstreet and Joe Hage take a break from their 132-mile trek down the Potomac to interview Belle Haven Dockmaster Chip Johnston who has been playing and working along the Potomac since he was ten years old. Chip touches upon the many users of the Potomac, improvements he has seen over the years and what he thinks will help ensure a Pure Potomac.  See a map of their route and check out more blogs and photos from the Island to Island Trek.
