An afternoon by a local lake in Golden Gate Park, traffic behind me and filtered through trees, joggers and baby carriages this way and that but not too numerous, the more prominent motors heard here not of street vehicles but of tiny little remote-controlled boats that enthusiasts bring to the manufactured water feature and race around regularly amid geese, turtles, and the occasional surface-breaching fish. The scene this past Saturday afternoon, banh mi and ebook in hand, was much more idyllic in person, I assure you. The birdsong was more prominent and diverse. The sense of space was less constrained. And the growling gusto of those hobbyist machines was significantly reduced in the context of the boats’ minuscule size.
