If I complete my work at the Eisenhower Presidential Library early, I am definitely going to check this folder out. This folder represents just a moment in time in squirrels-on-the-lawn history, but I suspect there might be material in other presidential libraries.
If you put it in a longer historical context, look into the squirrel stampedes in the 1820s

(Don't be fooled by "migration," everyone calls them stampedes or invasions).
There’s an on-camera story from Reagan in which he says he started feeding the squirrels and they came to expect it. Surprisingly he seemed not to be making an ideological point with the story.
