I played little league in the late 60’s. It was rare that any parent made a stink. The coach was the boss.
Different generation. My parents were born in the early 1930’s and respected authority and let us kids be kids.
I don't remember a parent yelling at a coach or umpire ever.
All I'm saying was it was a different time. Kids were allowed to be kids and expected to behave themselves without constant parental supervision. The parents didn't have to micromanage their entire existence.
I remember dropping my own son off at practice in the 1990s. Pretty much every kid had parents in lawn chairs and coolers watching every minute of practice. Never saw the point of that.
