Event on 7/28/05 in San Francisco. Marc Baum and Judy Mahnke with their daughter, Sarah Mahnke-Baum, 5, at home in their Cole Valley home. Marc is a musician and Judy teaches social studies at a public high school in the city and has seen first-hand how little state funding the public schools get and everything they're losing. So they are scraping to pay $19,000 to send Sarah to kindergarten at Katherine Delmar Burke School, a private school. Chris Stewart / The Chronicle
