Did you hear about the "electronic rangers" you can now rent in Death Valley National Park? For $15 a day these gadgets, which you place on your rig's dashboard, will give you a guided tour of the park. Park officials hope these devices, among other things, will generate a new revenue stream for Death Valley.

Imagine taking the time to go into your backyard, or the nearby woods, or even a pond close to your home, to catalog all the life you found in it.

At Great Smoky Mountains National Park they've been working on just that, and what they've found has been incredible.
