Racers, Rainbows, and Romans

I love the way being in Europe can mix fun and fascinating sights, sounds, and ideas. Here, in the space of about two minutes, we size up a tiny country from above, listen to (but don't see) a famous car race, catch a rainbow marking an international border, consider how the Alps stretch from the Mediterranean at Nice all the way to Vienna, and then marvel at a towering propaganda monument erected by the Romans 2,000 years ago (La Trophée des Alpes). That's our puzzle and challenge as we travel: to experience the entire range of Europe and weave it together so it has meaning.
