Officials at Wisconsin's Middleton High School are demanding that parents stop hosting a lunch each day at a park near the school. Students are free to leave campus for lunch, but school officials insist that the park is part of the campus because it has a lease on it. They say that the lunches violate school rules because the parents aren't following food safety standards and aren't checking in as visitors. Parents say the school officials are upset that the lunches feature Christian discussion. They also note that the school's lease on the park does not bar the public from using it and that they themselves rent the park pavilion.
