"Kevin Grange details nearly everything that possibly could go wrong in a national park and yet still manages to make you more excited than ever to hit the trail." —Conor Knighton, New York Times bestselling author of Leave Only Footprints: My Acadia-to-Zion Journey Through Every National Park Wild Rescues is a fast-paced, firsthand glimpse into the exciting lives of paramedics who work with the National Park Service: a unique brand of park rangers who respond to medical and traumatic emergencies in some of the most isolated and rugged parts of America. In 2014, Kevin Grange left his job as a paramedic in Los Angeles to work in a response area with 2.2 million acres: Yellowstone National Park. Seeking a break from city life and urban EMS, he wanted to experience pure nature, fulfill his dream of working for the National Park Service, and take a crash-course in wilderness medicine. Grange's epic journey took him to Yellowstone, Yosemite, and Grand Teton National Parks where, among other calls, he battled to save the lives of a heart attack victim at Old Faithful, a hiker who'd fractured his skull below Yosemite Falls, and a snowmobiler who launched into a deep gorge in the shadow of the jagged Tetons. Grange was initially overwhelmed—and out of his element—providing patient care in an extreme environment with limited resources and a two-hour drive to the nearest hospital. But he came to enjoy the challenges and steep learning curve of wilderness medicine. Between calls, Grange reflects upon the democratic ideal of the National Park mission, the beauty of the land, and the many threats facing it. With visitation rising, budgets shrinking, and people loving our parks to death, he realized that—along with the health of his patients—he was also fighting for the life of "America's Best Idea."
