People watching is great! (The kind where you watch people, not the other kind where they watch you having sex with your Finnish girlfriend in the alley, although that has it's attractions as well.)

People come in extremely wide-ranging variety, all different sizes and shapes, and with outlandish plumage. I like going places that draw big crowds of all different kinds of people from different walks of life and different socio-economic backgrounds, becasue then you gest the best variety. Shopping malls are OK. County fairs are good. The bach is always good too.
