need advice re praying in school

[Danzig]

i live (red) neck deep in the bible belt. my kids went back to school on monday, and the new principal at the high school brought in a gospel group monday morning, the first hour of school was spent in the auditorium while they sang gospel songs...and then had a prayer. tuesday and wednesday, a student led prayer over the intercom after the pledge....

couple questions...one, isn't this unconstitutional???? last i saw it was. now, i don't want to get into a debate of whether prayer should or shouldn't be allowed.
i'm ticked that my kid is going to school at a place where the supreme court ruling is being ignored. or should i be?

am i wrong? i called and left a message about this yesterday am at the school, and today they had another prayer, which means my call was basically ignored.

if i want to pursue this, who do i call? state board of ed? or do i just ignore it, like other things i don't agree with there??

i don't want to get too public about it...i don't want my kids getting grief about it.
