I drove through South Park to get to the hot springs. This is neither as cool nor as funny as one might imagine. There is nothing particularly exciting about the real-life town aside from its name, and most of its inhabitants (from what I could tell) weren't very geometrical or funny and didn't speak in strange voices. In fact, I took a photo, but was driving through rather quickly, so I didn't get a chance to focus on anything. Still, I've looked at it and I see nothing strange, funny, or copyright infringing about it (click to enlarge):
