Well as much as I loved the show at Seaworld and as much as I'd love to work at a place like that I can't help but wonder....

Orcas are animals that travel long distances. I can't say I'm surprised at the animal's behavior. You see the size of those orcas and the size of their tanks and it suddenly seems very small to me. They said the orcas were acting strangely and so they left them alone. Zooming around the tank sounds like the orcas were stressed out about something. For all we know, they are stressed with the size of their enclosure, the hundreds of people that watch them everyday, diet, etc.
