Last-chance Lifeline Nearly 6 million visitors each year come to San Francisco's Golden Gate Bridge - most for the scenery, some for the fall: 220 ft.straight down to the water. A total of 973 people are known to have leapt to their deaths here. Soon those who get as far as the rail might discover they have one last chance to call for help - on a handy bridge-side telephone directly connected to a suicide prevention center. Supporters note that while a telephone line won't stop anyone from jumping a compassionate voice on the other end might.
