I would add that there were also a heck of a lot more kids. I lived in a suburb in those days. Our kickball games could have 25 kids on each side. Safety in numbers. I remember the big kids looking out for the little kids even if you were not related. Most moms were home and we had to be back in our yard when the street lights came on. (Late 1960’s-1970’s).
