Appropriate to hold political rally at public high school?

[Acer]

I would imagine that attendance by the students would be optional. Of course, why stay in class or sit in a study hall if you could go to an event like this, if only out of curiosity?

Anyway, 16 year olds may be immature, but they aren't idiots. In fact, they'll be a more skeptical audience than a rally full of sympathetic adults.
