When I was in grade school (early '70s) we also had to say the pledge. No one informed me whether or not it was voluntary at that time. At any rate, at some point it stopped, although I didn't notice that it had stopped until high school, when in American Government class we learned about the controversy.
In kindergarten we would start the day singing
My Country 'Tis of Thee. I'm not much into displays of patriotism, but I still have a warm spot in my heart for that song. (And imagine: if that one were our national anthem, they would only have to play it once when the British head of state visits the US, or vice versa!)
