I heart the NPS. Some years ago while exploring the North Georgia Mountains, I stumbled across a very tiny spot of land under NPS management. The trail was barely noticeable off the side of the road, but once you hiked into the woods for several minutes, you came across
this sight.
And, unlike the majority of other waterfalls in the area, you could actually get close enough to cool off in the water. One of the great beauties of the NPS is that you're free to explore most areas without handrails or walkways, meaning that you can really enjoy the area as long as you are careful and respectful. (Hey -- you're also free to die doing incredibly stupid things, too! Nothing prevents you from taking a tumble off the edge.)
