The next time you go, try to see Mount Carmel and Mount Tabor, especially Tabor. Those have pretty churches and beautiful views, and you might find some of the villages around those mountains interesting, as Druze live near Carmel and Bedouin live near Tabor. Sepphoris near Nazareth has incredible floor mosaics, and whatever you do, don't miss the Israel Museum in Jerusalem. It is awesome.

Isn't that where the Dead Sea scrolls are? Did I post earlier than my father in law was the first person to translate them? We even had a tiny scrap of them. They are sending some to the Museum of Man in San Diego in 2007. A prof at SDSU will be curating.
