Must have been a 'depression era' thing. Nothing going to waste.
As a kid I spent a lot of time with my great uncle also. He was an avid outdoorsman. I have an old pics of him with squirrels tied to a piece of twine. Squirrels are draped around his neck and reach from one foot to the other. He was 6' 7" tall. When my great aunt would fix squirrel for him it would be three whole squirrel on a platter. The squirrels would be skinned,gutted with feet and tails removed.
I used to watch him eat them, brains and all. Course the squirrels were watching too.
Although I never ate the squirrel brains, for Sunday morning breakfasts, he and I ate scrambled eggs and fried calf brains.
