Pompaii

I would definitely call our stop in Pompaii impressive.  We were able to tour an ancient city that had been completely covered by the ashes from Mt Vesuvius where very few survived around 79 AD.  The city was left covered for centuries- and even now only a part of the city has been revealed to show us amazing similarities and differences from today to the past.  From similarities like "fast food" restaurants and baking techniques to differences like the local red light district where the different cultures of the past lead to "services" being displayed pictorially on the walls as "patrons" and lupa probably didn't speak the same language.  They still have the ruts from chariots on the roads which were not only visible but we were able to walk upon.  This was the closest we probably felt to being back in time and walking in their footsteps.
