The Air Force Academy is often referred to informally as "The Academy," "The Hill", "The Zoo" (originally "The Blue Zoo") or "Wild Blue U." Unlike the service academies at West Point and Annapolis, which are often referred to by their respective city names, the Air Force Academy is rarely referred to as "Colorado Springs." In athletic events, the Academy is generally referred to simply as "Air Force." Air Force Academy cadets and graduates are often referred to as "Zoomies."
