There's something about each city which makes them almost like a living organism, a person. The sights and smells of a Tokyo fish market, riding the front upstairs seat on a double decker bus navigating through London traffic, descending the Spanish steps in Rome, or walking the royal mile in Edinburgh . . . the surreal feeling of walking down the "Eixão" of Brazil's capital of Brasilia, the busy backbone highway which shuts down every Sunday for people to enjoy; or your plane almost touching skyscrapers as you land in San Diego, each city is unique and distinct.
