I know what you meant by “state flag” but I want to be cheeky, so here goes:

We didn’t pledge to a state flag but the federal flag. But the state of Maryland has a fabulous flag, and I’m still devoted to its design all these years later.

For whatever reason, in the 70s, in Maryland, I only recall pledging allegiance in the morning at the start of school during first grade. I don’t think we did it past second grade. In any case, I took the opportunity to insert curse words. I would say it like, “I pledge allegiance to the shit, and to the asshole for which it shits.” I didn’t lower my voice either. I just figured that I would never be noticed. Thinking back, I am surmising that my teacher must have noticed at least once but just ignored it.
