Thanks SDG
That explains it. It also explains why I see many LDS churches near the high schools around here so that they are immediately adjacent.
I won't pretend to support it, because I think it is quite obvious the LDS are going out of their way to minimize any attrition of their flock from public schooling by sandwiching themselves inside it, if they can, or alongside it - which in the child's mind incorporates their religious teaching into their school day.
Having gone to CA schools seeing such activity is a complete culture shock. Our school district had even forbidden school grounds to be used before or after school for religious related activity, such as prayer groups, etcetera, since they are paid for by public funds.
It's an eye-opener.
