How do you solve a problem like Maria?

As we were waiting for our train conductor to call “All aboard” and blow the ridiculous little train whistle (they literally do this), we looked to our right, and approaching from the distance, with the river and mountains behind them was someone wearing a large floppy hat and carrying a guitar, walking merrily along.  I immediately said, “Julie Andrews??” and began singing “The hills are alive” – unfortunately it turned out to be a man dressed in khaki and a fishing hat carrying a guitar, and we were not actually entering into The Sound of Music.  Disappointing.  Yet amazing.
