I have been the wonderful beneficiary of being allowed to work on this project of 7 years as a volunteer worker. My very first day at the site I uncovered a ring that was over 1000 years old not to mention the myriad of of there treasures that found their way into my sifting buckets.
I truly love having he opportunity to touch the objects that we find, many of which are from the time from the Temple and and subsequent empires.
As a gentile, I would never have been allowed to access or touch items from the Holy Temple and now I can literally find and caress these objects.
I can't recommend this experience enough for anyone who loves history, Loves the Bible, or wants to have an easily accessible 'archeology' experience. The teaching is excellent and the emotional rewards tremendous. Try it - You'll like it.
