Vacationland: The Obamas Head West

The World
Tomorrow, in the midst of a string of health care town halls, President Obama is squeezing in a family trip with Michelle and his daughters. The Obamas will visit the Grand Canyon and Yellowstone National Park. The former mayor of West Yellowstone, Montana, Jerry Johnson, tells us how the locals are responding to the impending presidential visit. We are also joined by historian Douglas Brinkley, author of The Wilderness Warrior: Theodore Roosevelt and the Crusade for America, with a look at the nation's national park system and the ecological streak that makes up President Teddy Roosevelt's lasting legacy.
