While I am not the world's biggest opera fan, I know that there are plenty of people out there who are.  Verdi's Nabucco is an opera about the Israelites, so it stands to reason that Nabucco would be the opera performed at the historic Masada fortres.  Ya'lla Tours is the only travel agency in the United States arranging and putting together trips to this historic and unique event.  Quite frankly, the entire thing is just very cool.  So, check out the article and if you are an opera fan, find a way to go!
