Well, there were a lot of safety issues when we came. I mean, just for a keeper, even in the older exhibits for a keeper to open the transfer gate and tigers or bears, whatever, to reach up to grab the metal handle of the transfer gate, an animal could reach out right there. So simply having the park department welders come down and putting mesh, heavy duty mesh screens there, so that the keeper can work in safety. There were a lot of common sense. This is long before accreditation standards were established for zoos. But accreditation standards, in many cases, are common sense anyway, they’re common sense safety things. So that was a lot of the things we did. And then behavioral enrichment slash positive reinforcement, all of these things started coming into vogue.
