Book excerpt: Imagine serving as a park ranger for our U.S. National Parks! If you were a national park ranger, you'd spend every day in one of the most treasured places in America. You'd wear a special uniform, a hat, and a badge—but sometimes you might also need snowshoes or a life jacket. Maybe you'd track the movements of wild animals. You could help scientists make discoveries. You might even be part of a search and rescue team! You'd have an amazing job protecting animals, the environment, and our country's natural and historical heritage, from the wilds of Denali to the Statue of Liberty.
