Dangerous overcrowdng at the Aquarium by the Bay in San Francisco

Bad bad bad experience at the Aquarium by the Bay on 7/7/13.

We went into the tunnel area (where you are in essence inside the big tank). And they announced they were having a shark feeding. We (11 of us including four kids) waited in the tunnel where they told us to.

The tunnel has a moving walkway in it on one side of the floor that slowly moves people through the area. On the other side of the floor there is solid ground. At the end of the walkway is a waiting area for the elevator. As the show started they turned on the walkway and people started moving past us.  The walkway was wall to wall people.

As they turned on the walkway, the elevator could not keep up with the crowd pouring in off the walkway and it started to get very crowded there. We decided to try and get out because it felt unsafe in the tunnel. We squeezed onto the moving walkway (my wife first, with my two kids and then me).
