““Whatever the reason for wanting to escape, sane or insane, zoo detractors should realize that animals don't escape to somewhere but from something. Something within their territory has frightened them - the intrusion of an enemy, the assault of a dominant animal, a startling noise - and set off a flight reaction.... Animals that escape go from the known into the unknown - and if there is one thing an animal hates above all else, it is the unknown.””
