By Kevin Murphy KANSAS CITY (Reuters) – Seven chimpanzees used an improvised ladder from a tree to scale a wall and briefly escape their enclosure at the Kansas City Zoo on Thursday, a zoo official said. One of the chimps apparently pulled a log or a branch and leaned it against the wall of the enclosure, giving the primates a leg-up to the top, zoo director Randy Wisthoff said. “We had a ringleader,” Wisthoff said.
