One of the most glittering successes in the leisure-time field over the past decade is the Disneyland amusement park at Anaheim, Calif., near Los Angeles. At a time when other amusement parks, most notably the world-famous one at Coney Island in New York, were going under, Disneyland's attendance figures and revenues have soared. Walt Disney himself, before he died in 1966, conceived and planned the layout, but one of the men who helped him and actually selected the site was a young Stanford Research Institute consultant named Harrison A. Price. In the late Fifties Price left SRI to found his own firm, Economics Research Associates, which specializes in recreation economics and has figured in such other projects as Disney's Mineral King development in California, Walt Disney World in Florida and the Six Flags Over Texas amusement area near Fort Worth. ERA now is a wholly owned subsidiary of Los Angeles' Planning Research Corp. Recently FORBES reporter interviewed Buzz Price, along with two of his top recreation planning experts, Vice President James H. McCarthy and Senior Associate Douglas M. Hinchliffe.
