For several decades, Munro's boyhood friend Mike Cooley raised and lowered the United States flag at Munro's gravesite, daily walking three miles from his home to the cemetery. According to Cooley's daughter, for over 30 years he never missed a day, even when he was ill with pneumonia. Upon his death in 1999, a lighted flagpole dedicated to Cooley was installed to allow the U.S. colors to be displayed continuously at Munro's grave without the need to be lowered at dusk. Cooley was cremated and his ashes interred at the Douglas Munro Burial Site with the remains of the Munro family.
