In Toronto, my home, there is an iconic bridge (the "Prince Edward Viaduct," the construction of which was at the centre of Michael Ondaatje's classic novel, In the Skin of a Lion) that spans the Don Valley.  Like the Golden Gate Bridge in San Francisco, those looking to kill themselves would jump.  And so the city eventually, and after much debate constructed a barrier, what was called the "Luminous Veil".  Many thought it destroyed one of the city's great landmarks, but that it was worth it if it saved lives.  A recent study has shown, however, that all it did was moved suicides to other bridges in the city.  So San Francisco might be right not to mar the GGB if it only means that people will jump from other sites around the city.

I have been reading your thread of posts with trepidation, as I’ve been waiting for someone to bring up my alma mater’s infamous bridges.
