Yosemite National Park announces three changes to the way in which visitors make camping reservations for campgrounds operated by the National Park Service (NPS) in the park. These changes are being implemented in an effort to thwart and discourage misuse of the camping reservation system that all visitors currently use when making campground reservations within Yosemite National Park. https://www.nps.gov/yose/learn/news/recgovchanges.htm
