Walking through the city of Buenos Aires, we came upon a small square with a crowd of people surrounding it. One quick peek at this couple dancing The Tango told us we'd found something special. I've never seen two people so passionate about their art. All of their emotion showed on their faces and within their body movements. This wasn't a professional dance group either - they were locals who came to the square to showcase their talent. I've never been so transfixed by two people, and to have it happen so unexpectedly was a real treat!
