Dozens of people have staged a protest run through Valley Forge National Historical Park near Philadelphia after a runner and others were ticketed amid the government shutdown.
Since the shutdown closed the popular site, at least 20 people have gotten $100 tickets for allegedly violating the closure order, mostly for parking in the park.
Several running groups took part Sunday in what some called a "Patriot Run" to call attention to the shutdown. They ran on state and local roads that cut through the national park but remain open and are just a few feet from park paths.
The National Park Service says tickets have been issued at parks across the country. A spokesman says safety is a concern, given widespread staff furloughs.
