Secretary of the Interior Ken Salazar announced on Earth Day -- and in the middle of fee-free National Parks Week -- that his department wanted to host the public sans entry fees several more times this year.

From www.nationalparksonline.org:

"What better way to celebrate this Earth Day than to make it easier for all Americans to experience the breathtaking landscapes, amazing creatures, and the stories that make up our shared  heritage," added Salazar.  "By getting outdoors, we remind ourselves of our blessings and of the responsibility we all have to pass these lands on to our children and our grandchildren."
