I was looking back at my Knoxville review to see how I described that bear exhibit, and I found this:
Now we all know who to point fingers at
I have mixed feelings about the exhibit myself, but one thing I can say about it: I can't even remember if I saw any bears in it because I was too distracted by giant concrete trees. Is that a good thing? I don't know, but it sure left a lasting impression. I'd chalk this up as a similar entry to Tropic World: it's worth seeing once, if only to find out once and for all how you feel about mock rock... because you really can't talk yourself into ignoring it here!
I'd also be curious to know how much the bears actually use that vertical space; maybe this selection would be more understandable to people if there was a known behavioral benefit, like with gorillas in Howletts-style cages. Regardless, it's a fascinating enclosure.
