The All American Quarter Horse Congress (AAQHC) is known as the largest single breed horse show in the world. The annual event is held at the 360 acre Ohio Expo Center and State Fairgrounds in Columbus, Ohio, and is hosted by the Ohio Quarter Horse Association (OQHA). The AAQHC has multiple events in a variety of disciplines. Points and cash awards earned by individual exhibitors who are members of the AQHA, the NRHA, and/or the NSBA also count toward accumulative totals for year-end awards and recognition in the respective associations to which exhibitors are members.
