Would you donate your old National Parks home videos and snapshots to America’s finest living documentarian? Of course you would! Why wouldn’t you?

Ken Burns is starting work on a new documentary about the history and human experience of our National Park system, and he wants your pictures, movies, and stories.

He’s specifically looking for materials from the 1980s and earlier, and the folks at National Park Traveler have all the contact info you’ll need.

If you send something in, you won’t get it back, but if it gets in the finished documentary you’ll get a free DVD of the series … which is pretty nice. Those PBS box sets can get pricey.
