Captions : I want to turn the clock back to when people lived in small villages and took care of each other. Pete Seeger

Captions : I do a lot of speaking about energy and environment. But that’s more a second job than a hobby. Hobby-wise, I love the outdoors – hiking, biking, kayaking, swimming, scuba diving.
