I grew up in a small town in north-central Texas. Our family never traveled far. I sometimes tell people that my first visit to a foreign country was across the Red River into Oklahoma. But when I was 18, I started a journey that has taken me to places I never imagined: the Opera House in Sydney Harbor, the coast of New Zealand, fishing for piranha on the Amazon, volcanoes in Guatemala, a lighthouse at Banda Aceh, Indonesia, the pyramids of Egypt, Mozart’s home in Salzburg, the Docu Zentrum in Nuremberg, the Pantheon in Rome, Lennin’s Tomb and the Kremlin in Moscow. If someone told me in my youth that I would visit these places, I would have thought they were crazy.
