I haven't watched the video yet but my Mom was the waitress you would encounter overnight at the only diner in the small town we lived in. She told me about a National Park Ranger who came in one night completely flustered. He was also the overnight watchman at FDR's home Springwood. He said FDR's mother came down the stairs and was totally enraged at his presence and told him to get out of her house.
So he did.
No idea the date, time, name of the man involved - but what the hell was that about?
