Yup, Michigan originally. Hash browns were certainly a good addition. My mom would make casseroles to use up extras in the fridge, and it seemed pretty common with my friends’ families as well. She would also do bread pudding, which is like a baked french toast. Lots of bread, eggs, cinnamon and nutmeg, and raisins. Would warm up a piece and eat with maple syrup for breakfast.
Commodore basic on the PET computer, back around 1981-1983. My grade school had three of them in the library, and since my mom was a teacher, she would sign one out for summer break and bring it home if any were available.
