thank you for the prompt reply!

I agree with you about the "proofs". But the meaning of this thread is a little different.
It's more like:

Q- Ok, I want to go to Venice, apart for the standard shoots, I want to bring home something different!

A- (example) do you know that in Venice there is a small Jewish Ghetto (where the actual word "Ghetto" comes from!!!), where is possible to meet Jews in their traditional clothing, like at New York or Jerusalem?

or

A- do you know that Acqua Alta (exceptional high tides that floods some parts of Venice) is more likely to show in Saint Mark's sqaure and "fondamenta di Cannaregio" than in other parts of the city?
