Has anyone done any work on the Old Spanish Trail (OST)? I am driving the Sante Fe Trail home form Missouri next month. I bought a book that is a great highway guide with every possible point of interest. After finishing creating that route, I got out my books on the OST and have discovered that a lot of it is dirt. I think that along with a CDR that actually follows the divide, I am goung to try to ride the OST. Does any one have any tracks? I have Vegas to the Amargosa River.
