Diana was, for the 17th time, the tour guide for Arba Sicula's 24th tour of Sicily. I couldn't imagine a more perfect guide, particularly for a group of somewhat older Americans, most having roots in Sicily and then NY. Being perfectly bi-lingual is a rare asset, but one that's Diana. Her knowledge is like a history book--which is so important in history-rich Sicily. Almost everything we saw as part of the tour, or passed, she had an encyclopaedic knowledge of--from any of the ruins we passed, to Italian and Sicilan political history, to the Allied landings in WWII to the churches and other individual destinations. Interspersed with the history lessons were anecdotes, stories and even recipes for Sicilian delicacies. She taught us a "word of the day" in Sicilian, and often some colloquial expressions, and explained so many things that otherwise would be mysterious. She seemed to know everyone, everywhere, too. Diana's mettle was really tested, however when my father took ill on the this trip--she got the cabs, took us to the hospitals (two) and was the perfect intermediary and translator to an unfamilar health-care system. This escapade took one afternoon--thankfully when we had two tour guides on that day. We'll be forever indebted to her for her kindness and knowledge. I can't imagine any tour guide of Sicily being any better, honestly.
