It’s a warm summer day and I’m enjoying excellent views of pelicans, gulls, terns, and other waterbirds. Which national park am I in?

On a day set aside to celebrate the Earth and the environmental movement, the Interior Department and National Park Service gave us dollars and cents.

National park concessionaires, deeply concerned over what they see as three decades of stagnant visitation to the National Park System, want Congress to authorize better marketing of the parks, longer "high" seasons in the parks they believe would generate more revenues for infrastructure improvements, and expanded concessionaire opportunities in the parks.
