Park rangers, seasonal employees, and backpackers live deep in many national parks and interact with a range of postal facilities. Grand Canyon, Yosemite, and Yellowstone national parks have full-service post offices on par with those of any mid-sized American city. Other parks are served by postal contractors at part-time or seasonal facilities. Either way, the USPS is the only lifeline to books, movies, magazines, medicines, hardware, and other small articles that would otherwise be difficult to obtain.
