Bird for free at a national park on Saturday and Sunday, Aug. 14-15! National Park Service will eliminate entrance fees on those two days although other fees -- for camping, reservations and tours -- will remain in effect.

"This fee-free weekend provides an opportunity for individuals and families alike to take an affordable vacation or to explore a nearby park they have never visited before," said Secretary of the Interior Ken Salazar. "I encourage everyone to take advantage of the free admission to visit not only our greatest natural wonders but also our nation’s historic and cultural icons."
