The Rocky Mountain ATV/MCAMA Amateur National Motocross Championship is the world's largest and most prestigious amateur motocross racing program. The national qualifying program consists of 52 Area Qualifiers (February through May) and 12 Regional Championships (June), hosted at select motocross facilities across the country. The qualifying system culminates in the National Final (first week of August) hosted annually since 1982 at the home of country music star Loretta Lynn in Hurricane Mills, Tenn. Nearly 20,000 racers attempt to qualify in 36 classes for the 1,446 available positions at the National. Christened "The World's Greatest Motocross Vacation", the National event serves as a launch pad for some of the biggest names in professional motocross and supercross, including Ricky Carmichael, James Stewart, Ryan Villopoto, and Ryan Dungey. The national program is produced by MX Sports, Inc., a West Virginia-based race production.
