Dave talks to Ranger Kevin Sweeney from Lassen Volcanic National Park. After the 9/11 attacks, he found himself in need of natural solace and went to Joshua Tree National park in Southern California. A business major at the time, Kevin decided to change his career and life path, volunteered for the Peace Corps and then set out to become a National Park Service Ranger. He's been at Lassen Volcanic National Park and knows the backcountry in all four seasons. He also started up the Dark Sky Festival that takes place around the time of the Perseid Meteor Shower every August.
