Lewis and Clark GPS File and Book (Hardcopy)
A CD that includes over 850 GPS way-points (573 campsites documented in the journals and 300+ points of interest). The GPS file can be used with most standard GPS units so you can find them while travelling the trail. Each GPS coordinate includes a brief description of when/what occurred at the site so you can quickly recall what they did and said at that specific location. The book goes into detail about their travel along with 100's of pictures and maps. You can start anywhere along the trail and the GPS will find the nearest campsite and guide you to the next sequential site along the trail. Basically this is a tool for Lewis and Clark fans to get a "real" feel for the trail.
