National Park Service funktioniert nicht

Interactive Maps: Each park has a detailed map that includes points of interest, along with roads, trails, and other information to plan your trip.  The National Park Service App is the brand new official app for all 420+ national parks.  Find interactive maps, tours of park places, on-the-ground accessibility information, and more.  Unlike other apps, NPS Mobile takes authoritative information from park rangers and combines it with a great suite of features.  With all of these parks and a brand new app, it will take some time to finish creating content for each park.  This one single app includes every one of the 420+ sites in the National Park System, no matter how big or small.  The app was created by National Park Service staff—people who know national parks—to help you make the most of your visit.  Share Your Visit: Tell your friends and family about the fun things you did by creating and sharing virtual postcards with scenes from the park.  It’s like having a ranger by your side to guide your trip, giving you suggestions for places to go, directions to get there, and things to do once you arrive.  If you don’t find what you’re looking for now, check back regularly as our rangers work to complete the experience for each of our parks.  Accessibility: The app offers a fully accessible experience with tools to benefit visitors with accessibility needs, such as audio descriptions of exhibits along trails and roads and in visitor centers.  Self-guided tours take you to interesting places in the park.  It’s especially handy if you’re exploring remote areas in parks or concerned about data limits.  Amenities: It's the little—and sometimes not so little—things that can make or break a park visit.  Let a park ranger be your guide!  Take a bus tour or scenic drive? Visit a museum? Join a ranger program? Become a junior ranger?
