Beautiful in Blue

The island of Santorini (or what remains of it) has won awards from tourist organizations as the most beautiful place on earth.  The center of the island was destroyed in a volcanic eruption somewhere around 1600-1500 BC; what remains are soaring cliffs surrounding a deep blue caldera.  The white-and-blue town of Oia sits at the summit; lower areas of the island grow cherry tomatoes and grapes.  We visited Oia, had a wine-tasting at a vineyard, and bought some of those flowing white cotton Greek shirts that keep you cool while shielding you from the sun.
