An avid horse racing enthusiast who raised thoroughbreds, McKay founded Maryland Million Day, a series of twelve races designed to promote Maryland's horse breeding industry. The day-long program has grown to become a major racing event in the state of Maryland, second only to the Preakness Stakes day at Pimlico Race Course. It has spawned more than twenty other similar events at United States race tracks such as the Sunshine Millions.
