Thanks to Earl Weidner, Tony Turnbow, and Jerry Gandolfo for sharing their research with me. Thanks for editing are due to Jack Young and Rick Blond. Rick shared his photos of the Lewis and Clark Trail with me. Rick took these photos while using the Lewis and Clark Road Trips book on his travels, which makes them very special.
