Walt served as President of SNORE in 1973 and again an 1975 and also served as the chief race steward and eventually organizer for Del Webb’s Mint 400 Desert Race (1971-1988), which grew into the richest, largest and most successful off-road race in the country. In 1976 he founded the High Desert Racing Association (HDRA) and promoted a half dozen races each year around the southwest. In 1985, Walt joined with Sal Fish to combine the HDRA series (four events) and the SCORE International series (4 events) to create one major points series competing under one set of rules. The HDRA/SCORE Desert Series brought increased entries and sponsorships to both organizations and made it possible for Walt to realize his dream.
