I have just returned from Salzburg, Austria where I took the Sound of Music Tour. I learned this from the tour guide. In the opening sequence, where Maria is dancing in the hills and she hears the bells from the monestary, she starts running to get back. Well, geographically speaking, this sequence is all screwed up. First, the monestary is approximately 6 or 7 miles from the hill she was on. Hearing the bells from that point is impossible. And second, she sure covered those 6 or 7 miles rather quickly on foot!!!!!!!
