They can lie on the grass, clamber onto a platform 20 feet up on a chimp-style jungle gym and gaze freely at the open sky, the vista unbroken by steel bars...Julius' group is among 111 chimpanzees coming to Chimp Haven over the next 18 months from the University of Louisiana at Lafayette's New Iberia Research Center. They could be the vanguard of a much larger immigration of former research chimps on the way to the refuge in Keithville."
