We spent a few hours at the Calgary Zoo today. Sadly, I got "distracted" here on Canreef this morning, wound up running a little behind, and neglected to grab my DSLR.
For great zoo photos, you'll have to see fishytime's thread:

I did snap a few shots of the zoo's filtration room for the penguin exhibit on my BlackBerry that might be of interest, however.
The photos suck, but the operation impressed me.
I tried to get a few shots of their carbon units, but the glare was brutal. You can kind of see the big blue carbon tanks in this photo. They have three of them.
After seeing this room for this little exhibit . . . I really want to see the Vancouver Aquarium's filtration systems.
