We drove across the bridge on Wednesday, but it was so enshrouded in fog that we couldn't even see the top while driving across it.
Thursday we took a bay cruise. I took a bunch of pictures then, but it was still mostly foggy and hazy.
Today was brilliant and clear, so we trekked on over to the bridge for photos and also took the opportunity to walk across.

Please see the other images in my San Francisco Trip gallery.
