Congratulations  and happy birthday to the National Park Service, which celebrates 97 years this weekend. Here in California, we boast 26 national parks including a couple of the most famous,  Yosemite and Death Valley.

There's also Point Reyes and the Redwoods up north, Devil's Postpile in Mammoth, and right here in L.A. the Santa Monica Mountains National Recreation Area.

If any or all of those sound like a fun weekend outing, you're in luck. As part of the birthday celebration, all national parks across the country are free on Sunday, Aug, 25. 

That means no entrance fees anywhere.

For more we're joined by Scott Gediman a representative with Yosemite National Park and a longtime ranger.
