They embarked on a life of adventure and travel, which included among other places, a trip to Antarctica in the early 1990s. The McKay's were also involved with economic development and real estate in the Lakeland area. Kirk McKay passed away in 1994, but Sarah continued with the family's civic and business contributions until her death in September 2024. 

Dr. Sarah McKay was most recognized for her contributions to business, cultural and civic endeavors, educational initiatives, and philanthropy.
