We flew down to Phoenix to visit our son and his fiancé. However, first we went up to the South Rim of the Grand Canyon for a couple of nights. It had been 9 years since we had been there, and that was a very brief visit. Before that it was in Winter of 2004. It was very interesting to see the changes to some of the viewpoints and the very convenient shuttles that run through the park. Also, while in the past, you would drive right up viewpoints like Mather Point, now cars are kept further from the edge. You can take shuttles to the points, or in the case of Mather Point, it is a short walk from the new Visitor Center there.
