We played outside when I was a kid growing up in Michigan. It didn’t matter if it was winter or summer, we were outside most of the time.
In the summers we would play hide-and-seek until way after dark. There were a bunch of us and so many different places to hide that the game would go on for hours.
We also had a sandbox to play and dig in, though I do remember the cats liked “digging” in it too…which was a little gross.
