In my humble opinion I feel the elephant renovation is on way too small a scale to be worthwhile. The yard will still be only half an acre, not particularly naturalistic and sterile. Louisville has built state-of-the-art exhibits for gorillas and polar bears but elephants are only getting a minimal overhaul. This might just be me but I feel zoos should really go for it if they're going to exhibit elephants. Otherwise, phasing out seems like the best option. Dozens of zoos across the country have built excellent elephant exhibits to maintain strong programs with the species but Louisville doesn't appear to be doing so.
