Thank you. Yes, in person it was awe-inspiring. Like the Capuchin monastery in Sintra, Portugal, with its 'hobbit holes' that we visited in 2007 and the ruins of Pompeii in Italy where we went last year, this glimpse of ancient civilization really does fill you with a profound sense of peace. It's hard to explain but well worth experiencing. Petra sounds like an absolutely wonderful place to go for vacation. I'll have to look into it thoroughly. Thanks for the recommendation. :)
