Hi, it is now a national Park road with no trucks allowed.Indians once drove pigs down it . We drove up on one end to a park and turned around to finish our work . Mena or Arkansas Chamber of Commerce or maybe Oklahoma have maps and brochures and history on them. for 45 or more miles it is comparable to the Smoky Mountain or Apalachian Trail from Cherokee, N.C. to Gatlainburg, Tenn. and on. Most of it is in Southeastern Oklahoma. circling the Lake above Broken Bow. That is rough and beautiful country. Take care, Charles Wyly
