Many years ago, I visited Vienna and joined an early morning coach tour to Salzburg. Our tour guide led us on a walking tour from the Salzburg city center toward the site where the film, the Sound of Music, was shot. Sixty minutes, several turns, and many gardens later, we arrived. The scenery was spectacularly amazing. After guiding us through the intricacies of the movie site and explaining the mysteries of the location, the guide told us we could start our free time to enjoy lunch and explore further on our own. Before he took leave, he told us to make our way back to the city center by 4 pm sharp for our return to Vienna, or risk being stranded in Salzburg.
