The name had me puzzled and amused. Unfortunately Google exists to clear up all mysteries. As it turns out R.O. Heater (1894-1971) was “Mr. Cary” during the middle of the last century, promoting the town and investing in the community with relentless energy. Heater was a member of the town board, a leader in the Methodist church and a master of the Masonic Lodge, according to Around and About Cary. He was also a Wake County Commissioner from 1946-1954, the last four years as board chairman. Oh well. The town of Cary thinks this park is rather spartan, but this verdant gem has a special place in their town.
