The Penny & Jock Fortune International Chimpanzee Complex includes three main areas, which are all connected by an elevated trail -- a "chimpanzee highway," so to speak. This living arrangement gives the chimpanzees the freedom to decide where to go, what to do, and who to do it with. Starting Saturday, May 25, visitors to the Indianapolis Zoo can watch chimpanzees...be chimpanzees. (WISH Photo)
