American Horseshoe Pitchers Association (AHPA)
Rules and regulations: http://www.oocities.org/bloomfield_99/ahpa_rules_index.html
Incorporated in 1949, AHPA prides itself in being able to promote horse pitching not only as a sport, but also as a means of enjoyment for people of all ages. AHPA is an offshoot of the Grand League of American Horseshoe Pitchers Association, the first ruling body of the sport that was formed in 1914. After 18 years, while the League has established a set of rules, by-laws, and a constitution, and has granted charters to clubs and state leagues, some members thought it could still do more. Thus, in 1949, Arlo Harris, then President of the National Association, proposed several measures to provide incentives, recognition, and benefits to all pitchers - regardless of level of play (e.g., professional, amateur, etc.). The proposal, however, was disapproved, prompting several members to put up AHPA that aims to recognize all horse pitchers in the US - reinstating the name and providing a charter to promote leagues and tourneys and adopting the count-all system of scoring.
