"Mountain Shadow." Though its range extends as far east as northern Baltimore County and as far south as Montgomery County, the Bobcat is a mystery to most Marylanders.

"Chesapeake Releaf." Many of the streams, creeks and rivers that eventually flow into the Chesapeake Bay originate far from their destination. So, it's hard for many people to understand how pollution of streams and rivers affects the bay, arguing that distance equals safety.

This segment, specially underwritten by the Chesapeake Bay Trust, tells the story of how volunteers and organizations around the state are trying to clean up waterways in the Chesapeake Bay watershed by planting trees to filter harmful pollutants before they flow into the bay.
