It was feeding time for the sting rays, and the kids really enjoyed watching the divers feed them lettuce. Well, my kids did anyway. Our friends' kids (not quite 2 year old twins) have been watching Finding Nemo lately and thought the diver was there to take Nemo away, and they were NOT pleased to see him.

Can't see Cole in this one because he's not quite tall enough, but Chase LOVES the aquarium that you can crawl into:
