The 3 major river systems in SC are Santee, Pee Dee and the Savannah River systems. The landscape and topography of the state's Blue Ridge region make white-water rafting, kayaking, etc. exciting ventures. However, persons must register with the National Park Service to obtain permission for any of these activities. Private companies, such as Wildwater, Ltd. in Long Creek, organize rafting trips, as in today's lesson.
