Ah... the good old days when you got cereal to eat for breakfast... with the box to amuse you and possible toys and puzzles inside. ******* Jacks, too! My favorite, I guess, was the little plastic submarine with a metal lid on its bottom that you used to fill with baking powder and then drop it into the water where it would sink to the bottom until a bubble large enough to float the sub back to the surface where it would roll over and release the bubble, then back to the bottom again... boring after a while, but a kid can marvel at something so simple.
It was cooler back then and we got by with window fans, if lucky, but still sweaty nights in Mississippi.
