One of the best places to stand if you want to watch the world go by is by a central fountain in a european city. I stood in front of La fontaine des Trois Grâces in the center of Montpellier and no matter which way I looked there was something to watch. Sometimes quick, sometimes slow, but a lot of activity on all sides. Next time I should just stand there all day, stopping only for the occasional cappuccino and croissant.
