Well, one of the major events was the passage of the Endangered Species Act, because that made it imperative that we breed animals. And that was an event that certainly prompted a whole different philosophy in managing animals in zoos. We had the various humane societies, and animal protective groups that always come along and challenge us. Seemed to be more of a fundraising thing for them than anything. But we would try to accommodate them as much as we could. I remember in the early AAC, it was the early zoo vet meetings. I guess there were only two women that showed up there. Well both of them were from the humane societies and the rest were all guys.
