I just spent a week with 35 sixty graders at http://www.gsmit.org/, one of my favorite places. We spent a day at Cades Cove hiking around learning about the early settlement and human influence on the Cove. If you ever get a chance to visit it's a really neat place. The park service has preserved several of the original home places. The cove has a problem with air quality due to all the cars going through. This time of year till fall it can be kind of hazy. Here's a few pics. I threw in a little dove tail action in one of the pics.
I should have thrown in this disclaimer at the front. The first picture is of the Middle Prong of the Little River, and the second is of Spruce Flats Falls in Treamont.
