[1]  [DOC] The Forum is a multi-purpose indoor arena in Inglewood, California, adjacent to Los Angeles. Located between West Manchester Boulevard, across Pincay Drive and Kareem Court, it is north of the under-construction Los Angeles Stadium at Hollywood Park and the new Hollywood Park Casino. It is about three miles east of Los Angeles International Airport. Opening on December 30, 1967, the Forum was an unusual and groundbreaking structure. Architect Charles Luckman's vision was brought to life by engineers Carl Johnson and Svend Nielsen, who were able to engineer the structure so that it had no major support pillars. This had previously been unheard of in an indoor arena the size of the Forum. [END]
