Okay, well, at least that's a bit more palatable.
I'm not sure if it had to do with the age of the building, but one issue with the indoor penguin exhibit it is would constantly steam/mist up on the glass, making it difficult to see things.
While I'd miss the "snowy" indoor environment, a more elaborate outdoor penguin exhibit with better viewing is okay with me. Good thing I've done the penguin experience backstage tour already (and got to see that baby penguin!).
