<p>I was referring to the lakefront and not the beach; yes, people gather there on an impromptu basis, but I meant more that the outside architecture could be “shaped” in a way to encourage spontaneous interaction - either by having little kiosks for refreshments or by having aspects of the environment you could interact with. This is a silly example, but in Geneva there is a park which has those large chess pieces - people walk by and start playing chess with one another, it becomes more of a public space. That kind of idea.</p>
