Sunland Park opened in 1959 as a thoroughbred race track.  It’s where jockeys Jerry Bailey, Pat Valenzuela, Cash Asmussen, and Willie Shoemaker got their start. In 1999 Sunland Park opened its casino and began a new era of unparalleled success. Management at Sunland Park recently made a decision to replace ScentAir masking agents in favor of Casino Air Technology.
