Highways Maui District praised the husband-and-wife team’s personal commitment to caring for Hāna Highway between mileposts 8 and 10, a two-mile segment adopted by Ensign Hawaiian Art and Hypnosis Hawaiʻi, the names of John and Barbara’s respective businesses. The duo has been picking up litter along their route every few months since 2016, typically removing 10 bags of trash each time.
