New slats make the Golden Gate Bridge sound like a David Lynch movie
I don't live in SF but have visited a few times.  I would be incredibly angry if someone arbitrarily decided to add a whole bunch of noise into my environment for no good reason.  However "interesting" the noise may be to some people, having to deal with it in my daily life would be awful!  I cannot comprehend how a person or group could be allowed do something like that.
