FYI- The Merry Wives Cafe is closed for business, but why not drive through Colorado City, and head out to Toroweap? It's such a beautiful, and historical area. You can stand where John Wesley Powell, and his men stood when they were looking for their lost men. There's camping there which is actually quite nice.
Me looking over the edge, and hiking at Toroweap on a 100+ degree day- UGH!
