In 1989, Leon moved to Australia and began working in the gold mining industry where he excelled at driving massive mining equipment. Leon moved to the U.S. in 1995 to open a paintball facility. Tombstone Paintball Park opened in 1998 and as a matter of course; Leon built a race track throughout the park which he used to test his new RX-7 rally car. Until its closing in 2006, Leon and Tombstone hosted countless rally cross and rally sprint events for groups like the California Rally Series and the Gravel Crew.
In 2000, Leon competed in his first American rally, Rim of the World. That year he finished the season in third place overall in the 2WD category and also won the rally cross series. 2001 was not a good season for Leon whose Mitsubishi Galant suffered endless mechanical problems. 2002 saw success for Leon and he won the Western States Rally Championship, the SOPAC championship and the California Rally Series championship in an Audi Quattro which also enjoyed two overall wins.
In 2003, Leon moved up into a Mitsubishi Lancer Evolution 6.5 and took a shot at the SCCA ProRally championship with mixed results. In 2004, Leon took a serious run at the ProRally championship in a new Evo 7. Leon won two significant rallies that year- the Colorado Cog Rally and the Pikes Peak International Hillclimb and Rally. Leon’s wins and consistent finishes earned him the ProRally Championship, but his most meaningful accomplishment was winning the Lovell Freeman Cup at Pikes Peak, an honor given to the highest placing rally car in the event in memory of Mark Lovell and Roger Freeman.
