National Parks Week: Pick Your Favorite
The National Parks: America's Best Idea, a six-episode series that airs this week on PBS, with tips about enjoying and protecting our natural heritage.
Tip #3: Show Your Support
Channel your inner John Muir and become an advocate for wilderness preservation. It could be a rewarding experience: Add your name and the name of your favorite park to the Sierra Club's list of 100,000 Champions for National Parks by October 4 and you could win a trip for two to Yosemite and San Francisco.
