For her birthday, Heidi and I went on the Penguin Experience Tour at SeaWorld San Diego.

From www.seaworld.com:
"Learn all about warm and cold weather penguins on this 1-hour tour. Guests will have an opportunity to go behind-the-scenes of our Penguin Encounter where they will meet an aviculturist and interact with a penguin. This is a side of SeaWorld most people never get to see."
