National Park Week 2011

America?s 394 national parks offer many close-to-home
opportunities for outdoor recreation. A growing number of doctors even write
?Park Prescriptions? to get patients outside and active. The growing
connection between public lands and public health is the focus of National Park
Week, April 16-24. Entrance to all national parks is free throughout the
week.
