A sad record for the Blue Ridge Parkway has been noted in a report by the Centers for Disease Control and Prevention. During my career I had to investigate and deal with the aftermath of numerous suicides within the park. I was even called upon to assist investigations in other jurisdictions and parks due to my less than desirable experience.
You can read more about this issue in my book A Park Ranger's Life: Thirty Two Years Protecting Our National Parks.
