"Guessing is dysfunctional, ignoring prior experience is denial.  Using valid numbers to project performance is rational."  - Quote from Harrison "Buzz" Price

Best known as the man who did the first viability studies for Walt Disney's projects, including Disneyland, Harrison "Buzz" Price is credited with founding the feasibility analysis segment of the attractions industry.  The Price Leisure Group applies the Roller Coaster Math approach learned from David Price's father who was the acknowledged dean of recreational economics consultants, having conducted all of the site location and economic feasibility studies of Disneyland and Disney World.
