Baton Rouge Magnet High School ninth-grade geography students, including Taylor Kimball, center, and Caleb Shilling, foreground, sit below walls marred by peeling paint and plaster Wednesday. Since officials announced plans in July to demolish the high school, alumni and others have started a digital campaign, including a Facebook group and an online petition, to save the building. A list of contacts and Web sites is included at the end of the story.

Barbed wire and crumbling plaster greet visitors, students and staff at Baton Rouge Magnet High School. School system officials say a complete renovation and modernization of the building may be too expensive.
