A prosperous school district was subject to a court-ordered desegregation plan involving busing. After receiving the court order recognizing that the district had achieved unitary status, the district decided to discontinue busing service to the elementary school and move toward a neighborhood plan that would transport sixth grade students to a school intermediate. Parents and citizens questioned the end of busing in elementary schools, claiming it would re-create segregated schools.
