My teacher in first grade or kindergarten informed us that we had to take off our hats (Except the girls didn't have to because of some rule that women's hats went with their outfit so they didn't have to take off their hat.) This was in about 1990.
I believed this for a few years and, upon deciding whether or not to wear a hat that day, I would always decide, "No, I'll save this and wear it for the flag salute."
