Finding Salzburg, Dreaming Naples

I once read somewhere that the three most beautiful regions in the world are Salzburg, Constantinople and Naples. I was fortunate to have seen Salzburg and I was not disappointed. Now I have made it my lifelong quest, time and money permitting, to see the other two -- Naples, where I will learn to make gelato. And Constantinople, now Istanbul, to see the famous whirling dervishes, who incidentally are all male.
