During the summer of 1972, the New Trier High School of Northfield, Illinois conducted their sixth annual seminar in community affairs. The seminar began on June 19th and ended on August 4, 1972. Participants included junior and senior high school students from all walks of life and from numerous geographic sections of the Chicago Metropolitan Area. During the seminar among their activities was a survey of Rapid Transit passengers who boarded the Chicago Transit Authority El lines at the Howard Street Northline Station. The survey was conducted entirely by the seminar students under the leadership and guidance of their director Mr. Jamie McClendon.
