One way to celebrate the 100th birthday of the National Park Service is the Every Kid in a Park program.
Every Kid in a Park is a White House initiative in partnership with Federal Land Management agencies to help engage young visitors and create a new generation of park visitors, supporters, and advocates. With their own Every Kid in a Park pass each 4th grader in the country has free access to national parks and historic sites, wildlife refuges, and more until August 31, 2016.
