Here is a link that includes a few photos of sights at the Steinhart Aquarium that we used to enjoy without ever having to pay an admission fee. Enjoy!

Wasn't that when they added the big dolphin tank? That quickly became one of my favorite exhibits during "feeding time(s)" and I remember it was usually crowded with other spectators as well. I guess it was the Aquarium's version of the Zoo's Lion House...without the noise level.
