Very VERY cool!
That part when he's petting the fish it is pure gold!
I got a couple of lil' ones lined up. The other day I was in Mission Bay with good friend's 6 year old. We rocked greenies and lizards on small chovies, had a blast!
The kids get that plain joy fired, it's cool to watch. We all remember when it was lit up in all of us.
It's cool that you carefully planned it, played safe, and got a great trip. Lil' ones can be quick and unpredictable. Very cool, your 3 year old is IN now... hooked!
