#NationalParkWeek kicks off with a fee-free day to encourage everyone to find something new by visiting a national park, especially one that may be close to home, a park you haven't considered visiting, or one you never realized is a national park! What new national park will you discover? NPS Video: Closeup of pine cones and birds singing at @princewilliamforestpark #sParkDiscovery #nationalparkservice #virginia #outdoors #nature
