OK, this is rather unfair. A whole swarm of people are dangling from this bridge and the police don't interfere?! That isn't a typical experience with police that a historic bridge photographer might experience when engaging in such legitimate activities such as climbing up or under a large bridge for the purpose of proper photo-documentation. I have been escorted off large bridges merely for WALKING ON THE DECK.
Ironically, the article says the police DID shut the sidewalks down. So the people were allowed to dangle, but you couldn't walk on the bridge?
