The chimpanzees access Young’s Hill, their two-acre outdoor habitat, through a doorway in the greenhouse. Missy is sitting in front of that door in this photo:
During the day, the chimpanzees spend a lot of time in front of this doorway looking out toward the hill. I think as much as they like being outside, they like the possibility of being outside almost as much. Today I caught some of the chimps taking turns sitting in the doorway and considering the possibilities.
