Does anyone know Sicily reasonably well?

I have a young friend who will be travelling to Sicily in six weeks. This is her first big trip, and I was hoping that someone on this list would have a passing familiarity with the trains, buses, etc and be able to give her some general advice. I am kicking myself for losing contact with every actual Sicilian I have ever met …

Fingers crossed, you can comment here or email me at blamebrampton@gmail.com, and thanks in advance!
