The marvelous, witty travelogue is almost as old as I am. Whenever I mention I grew up in South Dakota, older film buffs ask me about this movie and its climactic sequence at Mount Rushmore. Since, after my graduation from high school, I worked at Mount Rushmore, I have to tell them that the sequence was done in the studio. There is no open land with houses directly behind the Presidential visages. And I should know: I climbed the mountain the summer I worked there, and stood atop the faces of Washington and Jefferson and Roosevelt and Lincoln.
