Video: Yosemite Ranger Meets the True Owners of the National Parks

As we edge closer to the 100th anniversary celebration of the National Park Service later this week, this video gives us a good reminder about what those parks are all about. The clip, which comes our way courtesy of NBC News, introduces us to the true owners of these parks – the American people themselves. The national parks have been called "America's Best Idea" and for good reason. Prior to the designation of the world's first national park – Yellowstone – the idea of setting aside lands for the greater good of the public was completely unknown. Now, there are thousands of national parks around the world, with more being created on a regular basis.
