People coming to view the remains of the 35W bridge collapse

I think it is part of human nature to go and view scenes of destruction. Some call it grizzly curiosity, some an achnowledgement of our impermanence, some to pay respects. So many different reasons. The stone arch bridge runs close by where the bridge collapsed - it was filled with people coming for whatever their reasons. I took quite a few pictures of people's silohettes as the sun was setting - kind of paradoxical to see them standing on a bridge to view another's collaps - of course I was up there looking just a half hour before.
