On January 11, 1908, Theodore Roosevelt dedicated the Grand Canyon as a National Monument. It wouldn't achieve National Park status until 1919.
I encourage you all to think about how much the National Park Service offers American citizens. I am, personally, extremely thankful for their work and service.
While a good number of National Parks are free to enter, this weekend (January 14-16, 2012) everyone can take advantage of Free Entrance Days in the National Parks. Get out, see some sights, and revel in the beauty of our national landscape and history!!!
