it is a bit of a family tradition for Ezi.  My mother-in-law used to go on archeological trips and take courses all the time.  The attraction of Israelis to what is under our feet is very strong.  I used to think it was connected to proving our biblical lineage, but it seems to be much more.  On our trail, every little dig is examined in detail – the Philistine temple, the Canaanite idols, the neanderthal graves, and, of course, the Jewish sites.
