We went to the aquarium in Long Beach a couple weekends ago. It was a lot of fun...although Rowen lost interest in all the fish after awhile. We have come to the conclusion that he is quite the hands on little kid...so if there isn't anything to touch or interact with he isn't really interested.
But when it came to the tide pools or petting the sting rays, Rowen was all about it. He did LOVE to see Nemo and Dori live and in action (as seen below ha ha).
