It was a cute shop and the person running it was very informative and friendly. If you ever find yourself between the grand Canyon and Vegas, make sure you stop.
We stopped at the Hoover Dam on the way to the Grand Canyon. We did the self guided tour, which included the visitor center and the top of the dam.
Halfway across the the dam is the Stateline between Nevada and Arizona. The plaque is only on one side of the street.
