Buenos Aires, Argentina
The Last TangoPretty much everywhere you turn in Buenos Aires, some couple has broken out into tango and attracted a crowd.
To be fair, this spectacle is mostly for tourists but no where in the world does anyone else do this. As kitschy as it may appear, it's actually quite sexy and sensual, as the tango is.
But tango is no joke in this city. Dance halls abound for the many who take this sultry dance very seriously. I imagine the street expos must belittle their craft in some way.
Still, to watch a couple get all steamy right in the middle of the street, at the drop of a hat, is truly an Argentine phenomenon.
