WACKO

WACKO was the "Westchester Academic Challenge of Knowledge Organization", which operated until 2020 in Westchester County, New York. While most of its teams came from its home county, some came from the areas of Connecticut that border Westchester, usually in Fairfield County.

Operated by Les Roby, its largest event was the Omar Q Beckins Academic Challenge. It universally used material from Questions Unlimited for all its events, which cemented QU's dominance in the Hudson Valley. It merged with MACC upon Les's retirement and is completely defunct.
