The pedestrian path across the Golden Gate Bridge ...

The pedestrian path across the Golden Gate Bridge is over a mile long. There isn't much to do once you get across other than take some pictures, turn around and walk back. Conveniently placed phones along the path, towards the middle are apparently to prevent suicidal people from leaping over the edge. Over a thousand people have done this, so its not clear that the phones do an effective job of talking people off the edge.
