Which side of the line do you live on? In 1954 the Supreme Court ruled that little Linda Brown couldn't be excluded from a public school because of her race. In that landmark decision in Brown v. Board of Education, the court famously declared that public education must be available to all on equal terms. But sixty-six years later, many of the best public schools remain closed to all but the most privileged families. Empowered by little-known state laws, school districts draw attendance zones around their best schools, indicating who is, and who isn't, allowed to enroll. In many American cities, this means that living on one side of the street or the other will determine whether you leave eighth grade on a track for future success or barely able to read.
